SHIPPED TO CALIFORNIA

    We have just completely gone through this one. As the "EQ", Tape Monitor, and Record switches do not respond to the normal, simple cleaning on these ADC's, all three control "push" switches removed, disassembled, contacts individually burnished and completely cleaned with solvent for trouble-free service. This is a time consuming process, but the best way to insure performance. We injected both channels with 1kHz sine waves, and monitored switch performance on an oscilloscope with no visible issues after switch re-build. All fader LED's function. Great quality, dual 10 band EQ. Built very well and made for great "sonic" performance. These were one of the most

   We have just completely gone through this unit. A thorough cleaning on this model requires most of the unit to be disassembled. All 'sealed' "EQ", Tape Monitor, and Record accessed and completely cleaned with solvent for trouble-free service. This is a time consuming process, but the best way to insure performance. All faders, flooded with multiple applications of De-Ox-Id. Both level potentiometers cleaned. New VU meter lamp installed. RCA I/O jacks scrubbed for clean connections. We injected both channels with 1kHz sine waves, and monitored switch performance on an oscilloscope with no visible issues after cleaning. Unit now tests perfectly.

We strive to make sure that all of our clients get the best usage of all the gear we sell. We strongly suggest that purchasers of our EQ's with pink noise generators and spectrum analyzers call us for advice on proper and full use of these types of equipment. We will be more than happy to walk you through the connection, set-up and use of this and any gear we sell. An EQ / Pink Noise Generator / Spectrum Analyzer is one of the greatest "tools" available for any stereo system, but only if utilized correctly.

TIME DELAY UNIT
Circa 1978-83

 
Very rare, high end stereo digital delay from API. Unit delays signal to add depth and spatial effect to sound. Can either be used on main front channel speakers or even better on the rear speakers for the "Live" effect. Unfortunately this one has one side lower in volume and distorts out of one of the outputs. Fix or use for parts. We have cleaned the controls and tested. Great effect. Cosmetically also in great shape. Solid real Walnut wood panels look nice. Made in the USA and very well built. Semi- "WORLD AC POWER" as it will operate at 50 / 60 Hz AC. Unit measures 14.75" in width x 10.25" deep x 4.5" high and weighs 9 lbs unpacked.

SHIPPED TO MISSOURI

  Our technician has completely gone through and 'Certified' this unit.

  Everything was completely tested and benched.

 
  Unit was disassembled for restoration / reconditioning.

  Both rotary potentiometers cleaned for quiet operation.

  Most I/O jack and fader solder joints re-flowed for trouble-free service. 

  
  Tape monitor and Attenuator switch locks checked for proper function.

  All 'latched' switches locking fine.

  We checked and replaced lamps where needed.

  We then tested both channels with a test tone and O-scope, analyzing both channels with and without each independent effect.

  It was then cleaned inside and out.

  All inputs tested and both side produces clean and even sine waves (checked with AF gen and oscilloscope)!
All functions tested for perfect operation. No power supply hum of any kind. It's dead silent!
 Unit is clean both cosmetically and sonically. Looks and sounds great!

CIRCA 1970'S

THE famous and VERY sought after, Expander / Enhancer! Just about every audiophile system has or should have one of these included in the signal chain! They really brighten up you sound and recordings making them come Alive! It covers all three bands of the audio spectrum, Lows - Mids Highs, set at 200 Hz and 4 kHz filter points. The expander can be positioned Pre or Post in the audio signal chain. Expansion is infinitely variable from 0-50% and the transition level can be varied by any amount 0-100. The Gain change readout ranges from -20db to +12db. This thing has a variable Dynamic Range of 101-115dBv! Frequency response range of 20Hz-20,000Hz. The series II also features a very important feature that the series I doesn't. A Bypass switch. Maximum input / output voltage of 6 volts so it can even work in a professional sound system. Is also rack mountable with optional rack ears (not included). Unit looks GREAT (essentially NEW) and sounds great! Linear slide controls have non-original knobs by Pioneer installed.  Measures standard rack width of 17" wide x 1.75" (1 rack space) high x 9.5" deep and weighs only 5 lbs unpacked. With original box and packing, and comes with a copy of the original DBX 3BX-TWO owners / users / operations manual. Includes our standard 30 day limited warranty!

 ______________________________

While we get email 'Thank-You' notes from a good amount of our customers, it's rare that a single model gets so many. The JVC SEA-10 is one of those units that pretty much every one that's purchased one has called or emailed to express how happy they were with it, and it seems like it would be a 'sleeper' unit. They really are fun to use, they are easy to use and they get the job done. Great design, build quality with no-excuse sonic quality and very easy to use. The JVC SEA-10, 5 / Pseudo-7-band "combined" stereo, graphic EQ. Combining the faders into stereo units, as opposed to separate left and right is so much easier to utilize for most users. One of the best built EQ's we had the pleasure to work on internally.

Very impressive and classy looking Phase Linear 1000 'Series Two' Dynamic Expansion / Auto-Correlator. Brushed aluminum face with matching knobs. If it weren't a 'consignment' I would probably be keeping it for my personal 'Phase' rack. From the Phase Linear 1000-2 users manual;
Proper use of your Phase Linear 1000 will allow you to reproduce music with less noise and greater dynamic range than previously thought possible. The Phase Linear 1000 is a dynamic range recovery system.Recording studios and record processing companies employ a number of necessarily evil techniques brought about by the state of the recording art. Taken together, these techniques may be described as processes which serve to limit and restrict the dynamic range of recorded material. Unfortunately, their use is necessary in order to put the tremendous range of live music onto the surface of modern phonograph discs and tapes. When used properly, the Phase Linear 1000 will significantly correct these shortcomings inherent in the recording process....The Dynamic Range Expander serves to greatly increase the available dynamic range...The peak restoration system is designed to restore to a significant extent the music peaks that are removed to the peak-limiter during recording...Tracking is designed to closely complement the dynamics of recording studio peak-limiter...The goal of this system is to expand the dynamic range of standard musical material such that the loudest passages will produce levels of 105dB and yet during quiet passages noise or hiss will not be heard (without the 'breathing / pumping often heard with other systems)
I can tell you from personally auditioning this unit after my tech finished with it, that it's fairly AMAZING! I tested it with a cassette deck that had Dolby B. I recorded a tape without Dolby, then played it back with this unit. It did an 'astounding' job of removing 'tape hiss' without reducing high frequencies like the Dolby did. It worked equally well with the 'Dolby Encoded' tapes. It also did a great job reducing the hiss in 'FM Stereo' broadcasts, so much so that it will be hard to listen to FM without it.

Phase Linear Series Two 1000 Features:
 

- Separate controls for "Correlation Threshold" and "Dynamic Expansion"
- Expander Threshold LED
- Low Freq Calibration
- Correlate In / Out
- Expander In / Out
- Tape Monitor
(Tape Monitors can be used with Tape decks such as Cassette Tape Recorders/ Players, Reel to Reel's, 8-Track Tape Cartridge Decks, Video / CD / DVD / VCR / DAT / MP3 / iPod / iPad / iPhone / iTouch / iGadget / MP3 / XM / SIRIUS CDR (CD recorders as well as for inserting signal processors, such as EQ's, Reverbs, Spatial Enhancers / Dynamic Processors, Noise Reduction units, Special Effects units, Time Delays, etc)
 - Input gain selectable for either 0dB or -6dB (so could work with stronger output gear such as 'recording studio' / 'semi-pro' equipment)

Phase Linear Series Two 1000 Specs:

Freq Response:
1dB 20Hz-20kHz
THD: 0.09%
S/N Improvement: 17.5dB (Dynamic Expansion System combined with 'Correlator')
Max 'Attack' rate: .5dB /
μSec
Input Level (average): 250mV RMS
Input Sensitivity Power Amp: >50k Ohms
Dynamic Expander: 7.5 dB expansion over a 40dB range of input signal, including approx 1.5dB of 'peak restoration'
Correlator Noise Reduction: High frequency noise reduction commences at 2kHz. Low frequency noise reduction begins at 200 Hz ultimately reaching 20dB at 20 Hz, passive subsonic filter rejection of -25dB @ 5 Hz. Weighted overall noise reduction is -10dB from 20Hz to 20kHz.


Again, we have completely tested unit for correct function and sonic quality. Looks like new and sounds great! Will include an e-copy / pdf download of the Phase Linear 1000 Series 2 owners manual, so you can appreciate the most out of the unit. Measures 19" wide x 3.5" high x 10" deep and weighs 7 lbs unpacked. Includes our standard 90-day limited warranty!

 Pioneer DT-570 Audio Timer. These were originally designed for setting your system to record scheduled FM radio shows and Album rock. They also can be used to turn your system into a Super-Hi-Fi Alarm clock radio and / or just as the ultimate and really cool digital clock.
This is from a collection of these that took us a long time to amass. Many of these will erratically change / advance the time after they've been on for 1 or 2 hours. This is one of the few out of the many we get that keeps time perfectly and was checked over a 1 week period. Entire unit was disassembled and cleaned inside and out, including the internal switches.  All functions test perfectly. This is the one with the Aqua Blue Fluorescent digital readout and black face plate. Use it to turn on most anything with a latched or mechanical power switch. Will switch up to 1200 watts via dual AC outlets. Unit looks near new and works great! Clock memory is volatile at power outages. Measures 16.5" wide x 5.5" deep and 2" high and weighs 4 lbs unpacked. Includes our standard 30 day limited warranty.

  Our technician has completely gone through and 'Certified' this unit.

  AC voltage selector corrected for North American AC Power / Current.

 
Everything was completely tested and benched.

  Most I/O jack and fader solder joints re-flowed for trouble-free service. 

  Tape monitor and Attenuator switch locks checked for proper function. All 'latched' switches locking fine.

  We checked and replaced lamps where needed.

  We then tested both channels with a test tone and O-scope, analyzing both channels with and without each independent effect.

  It was then cosmetically detailed inside and out.

  All functions tested for perfect operation.

  All inputs tested and both side produces clean and even sine waves!

  Checked with oscilloscope. No power supply hum of any kind. It's dead silent!

 
  Only minor cosmetic issues in that there are a couple of 'dark' areas to the upper edge of the face plate (not visible from a 'head on' view) and some light scuffing to the case / cover (see photos above). Overall, still looks nice and sounds great!

HEY, WHY ALL THE 'X'd' OUT / OMITTED SPECS AND TEXT?


 Okay, so here's the deal...this EQ is NOT for someone purchasing their 'first EQ', or someone who does not have a comfortable knowledge of 'signal flow' and 'signal routing'. It is fairly complicated to operate, and easy to get into a 'no sound' situation. Just a friendly warning. If you are familiar with EQ, and / or are willing to tackle a challenging learning curve with this on, then you should be fine.

 An EQ with a Spectrum Analyzer built-in that actually does something besides just look cool! The built-in, Pink Noise generator with jack for optional mic allows actual room / system analysis for perfect EQ adjustment of the audio playback levels at the available frequencies. This is a great looking and performing EQ and is built using quality, center de-tented linear controls with a full 60mm of throw! Again, we have completely gone through cleaning it, refurbishing & checking all functions. All controls and switches cleaned for worry-free service. Again, the no PN mic is included, but any decent, Hi-Z mic with a 'Flat' response from 30-18k will suffice. Includes a 'pdf / e-copy' download of the Pioneer SG-750 owners manual. Measures 16.5" wide x 10.5" deep x 4" high and weighs 10 lbs unpacked. Includes our standard 30 day limited warranty.

SHIPPING TO ELVIS IN NORTH CAROLINA

(The one with the LED's in each slider)

Our technician has completely gone through and 'Certified' this unit. Everything was completely tested and benched.

 Unit was disassembled for restoration / reconditioning.

 Most I/O jack and fader solder joints re-flowed for trouble-free service. 

 Tape monitor switch replaced with new as lock had failed (as they normally have by now) so we replaced both with fresh, new switches (should also be good for another 35-40 years)

 Attenuator switch locks had failed (as they normally have by now) so we replaced both with fresh, new switches (should also be good for another 35-40 years)

 2 of the linear faders were replaced with original, Pioneer pots (tech note; 66 screws removed to access, and 66 screws then replaced!!!)

 Balance of linear faders cleaned with contact cleaner

 We checked and replaced lamps where needed.

 We then tested both channels with a test tone and O-scope, analyzing both channels with and without each independent effect. It was then cleaned inside and out.
 All 'latched' switches locking fine.

 All inputs tested and both side produces clean and even sine waves!

 All functions tested for perfect operation.
Checked with oscilloscope.

 No audible power supply hum of any kind. Floor noise measured > -60dB! It's dead silent!

 With the exception of a bit of 'rash' along the top edge of the face plate (see photos above) the unit is in good cosmetic shape. Switch / Fader caps all 'shiny' with only slight amount of the 'corrosion / patina' we commonly see on about 70% of Pioneer units (just FYI). Unit is clean both cosmetically and sonically. Looks and sounds great!

- Overload indicator for attenuator
 - One un-switched AC convenience jack located on the back rated at 100 Watts


Again, our tech has completely gone through this unit and 'certified' it READY TO GO! Cosmetically, it does have a bit of 'rash' along a couple portions of the face plate, and a bit of the typical 'green' surface patina on the fader and push caps (no, we've never found a way to remove it, and it's becoming more common across the board on late 70's Pioneer gear), but nothing too distracting (see above photos). Perfect compliment to most any audio system

Unit was disassembled for restoration / reconditioning. Both rotary potentiometers cleaned for quiet operation. Most jack and fader solder joints re-flowed for trouble-free service. New tape monitor switch installed as the original no longer 'locked' (many of these units you see on the on-line auctions have broken switch locks, and it's not a matter of 'if', but 'when' they will fail after 30 years. We do sell replacements if you bought one of those units or have one). We disassembled the display and replaced lamps where needed. We then tested both channels with a test tone and O-scope, analyzing both channels with and without each independent effect. It was then cleaned inside and out, then polished to near new look.
 Unit is clean both cosmetically and sonically. Looks and sounds great!

Our technician has completely gone through and 'Certified' this unit.

Entire unit disassembled for refurb / bench check / testing / repair

I/O jack solder joints re-flowed for trouble-free service. 

All toggle switches cleaned (entire circuit board and patch panel must be removed to access). Cleaning ALL the toggles is a MUST-DO. Otherwise, these things are just 'paperweights'.


All 'latched' switches locking fine.

We then test both channels with and without each independent effect loop.

It was then cosmetically detailed inside and out.

All functions tested for perfect operation.

 
While the 'bats' (handles) on these switches are susceptible to breaking due to rough handling, all the switches on this particular unit intact and fine. (we have spare switches for these 'just in case'. Overall, still looks nice and works perfectly following restoration!
 ______________________________


Very versatile unit allows selection between up to 3 tape decks (Reel to Reels, Cassette Decks, 8-Track Decks, DAT's, CDR's, iPod's, MP3 Players, DVD Players,  Audio etc.) or up to 3 Audio Signal Processors (Reverbs, enhancers, delays, dynamic processors, EQ's etc.)

- Connects easily to the Tape-In / Tape-Out jacks on your existing Stereo Receiver, Pre-Amp or Integrated Amplifier. If you dont have a true tape-monitor or tape-loop you can also connect it simply to an input. You just wont have any record capabilities.

-
 
Bi-Directional Dubbing / Copying from one deck to another
- Can also be used to connect Signal Processors such as EQ's, Reverbs, Spatial Enhancers / Dynamic Processors, Noise Reduction units, Special Effects units, Time Delays, etc, instead of Source / Record devices
- Inputs could be used for turntables with the addition of a simple phono pre-amp available here
- Completely passive unit, meaning no power or power supply required for operation
- Toggle Switch routing eliminates the hassle of swapping patch cables and cords.


All functions test great. These are great "tools" to have in any audio rack. Greatly enhances the versatility of most audio systems. The unit works and looks great.

VINTAGE SAE IMPULSE NOISE REDUCTION SYSTEM
SAE 5000 RECORD 'CLICK AND POP' REDUCER / ELIMINATOR

Circa 1976-80

SOLD 2/12/19
SHIPPING TO RANDALL IN MICHIGAN

SAE 5000 Impulse Noise Reduction / Click and Pop killer. Great for use with any turntable / record player, even and especially handy for those old 78 RPM records. If you've got records that have been used as 'Frisbees', this may breathe some usable life back into them. You can 'dial' in how much 'click and pop' reduction you want. Before you're tempted to simply ask, "why wouldn't I just turn it to the 'max'", you have to realize "there's no 'free lunch' ". Like most 'noise reduction' systems, it's a 'fine line' between having a device remove offensive noise, and too much desirable material. The included operations manual is very thorough on the principal that the unit operates on, and how to best adjust it. While there's a couple of techniques to adjust it's 'Sensitivity', I personally utilize the 'Invert' function almost 100% of the time to determine how to set the 'Sensitivity'.  While it doesn't eliminated ALL 'clicks / pops' from most albums, it will certainly reduce the most annoying ones, and on some albums it may completely clean it up. Part of it's performance and results will depend on the recorded 'material'.
I have tested and used these units on MANY albums, and it used correctly, generally found no 'ill effects' in the way of 'diminished attack' of notes, 'sustain' of notes, 'depth' or 'presence' of notes, or really anything in the way of real 'negatives'. Of course there's no 'magic bullet'. If there were, such a unit would cost tens of thousands of dollars, and records would not have given so much way to CD's.

 Occasionally, I'll try my SAE 5000 on a record, and find that due to the type of recorded material, it cannot discern the 'static' from the material well enough, and I'll decide to 'defeat' it.  I simply look at it as one more way to possibly improve the sound and listening experience of your vinyl. Anything that can reduce and in some cases eliminate the 'clicks and pops' from your scratched and beat-up records is generally a plus. I use 'Monster Cable' (12G, OFC) speaker wire. I've done some pretty involved test and not heard a difference between that wire, and the 'cheapest' wire avail, but I know that 'technically' there's a difference, and it's cost isn't prohibitive for me, so I use it. I don't use three dollar RCA patch cables either. I will use RCA cables costing quite a few times more. Not because I've really ever heard a difference, but because, 'TECHNICALLY', I know there is. The SAE 5000 series Impulse Noise Reduction is a unit you can DEFINITELY hear an improvement with probably better than 75% of the time. That's an improvement that's DEFINITELY worth it in my book!
This unit is in great condition. We have completely gone through and cleaned all the switches, contacts, and the linear potentiometer. We also re-flowed all the solder joints on the I/O  Jacks.  Each unit is tested with a myriad of record selections for consistency. Looks good, functions and sounds great! Unit is narrow at 7" wide x 9" deep x 1.75" (1 rack space) tall and weighs ~3 lbs unpacked. Comes with a 'e-copy / pdf' download of the SAE 5000A owners / users manual. Includes our standard 30 day limited warranty.

Ps. SAE 5000 vs SAE 5000A Impulse Noise Reduction Systems. I have owned and extensively used both versions. I have never heard one 'iotta' of difference in any way between either unit. I've listened for difference in overall performance (ie; does one remove more noise than the other), distortion, punch, sustain, attack etc, on many types of music played with many types of instruments. I hear no difference with brass, strings, woodwinds, percussion, acoustic steel or nylon string guitars, acapella, male or female vocals, symphonic, jazz, R&R, Bluegrass or even my album of the "Dogs Barking Jingle Bells"  (just kidding, I don't have that one...yet.) You gotta figure they got it pretty 'right' with the original, as it enjoyed a 4-5 year model life. Most mfg's are going to try and 'new and improve' a unit every year or two.
Yes, if you crank it up, you'll get distortion on many of your albums from either unit, and if you simply put it on a 'scratched up lead in' section, you won't get much reduction from either unit (as there's no material for it to compare against), and if you put on an album that you used in high school as a Frisbee, don't expect much improvement with either unit. For normal use, with typically lightly scratched vinyl, you will almost always notice minimal to substantial improvement. Some times I don't use one, most of the time, I do. Just my 2 cents worth.

Our technician has completely gone through and 'Certified' this unit.
Unit was disassembled for restoration / reconditioning. All switches / controls cleaned. Springs, send and receive units inspected and re-soldered where necessary.
Both reverb spring junctions inspected and all send / receive coils in perfect, working order.  All display and power lamp sockets 're-sprung' and their lamps / bulbs replaced with new. All RCA I/O jacks had their solder joints re-flowed. Display 'slide' mechanism cleaned and re-lubed. Control shafts check for 'true' and straightened where necessary. AC power voltage and fuse checked for correct setting and proper value. We then tested both channels with a test tone and O-scope, analyzing both channels with and without each independent effect. It was then cleaned inside and out, then polished to look great. Floor noise measured to -60dB! Only issue cosmetically is a minor scuff on the top edge and a minor cigarette burn to the top vinyl (neither particularly distracting).
 Unit performs and sounds great!

It was then cleaned inside and out, then polished to near new look.
 Unit is clean both cosmetically and sonically. Looks and sounds great!


This is one of the better sounding, most "useable", analog processors we have ever heard! Period! Great 'Swiss Army Knife' unit for a project home studio as well. It gives you a stereo 7-band graphic EQ for the main program material, built-in 'Echo' and 2 separate microphone / guitar / keyboard input channels each with their own dual 5-band graphic EQ's.

______________________________

Sansui RG-707 Features:
 
- 1.3 Octave, 7-Band Graphic EQ
- 2 Additional Channels for 'Mono Inputs' such as Microphones, Guitars, Keyboards, Drum Machines or any device via 1/4" input jack
- Built-in 'Echo / Reverb' effect with multicolor display, level control and 'Assign' function
- Each of the separate Channels have their own '5-Band', Graphic EQ
- Independent Level controls for Channel 1 and Channel 2 of the 'mixer' function

- +- 12dB Cut / Boost (most do only 10 dB)
- Main EQ; 7 frequency centers are as follows (starting at the low-end):
63Hz - 160Hz - 400Hz - 1kHz - 2.5kHz - 6.3kHz & 16kHz.
- 40mm Linear Faders
- Tape Monitor (Tape Monitors can be used with Video / CD / DVD / VCR / DAT / iPod / MP3 / XM / SIRUS CDR (CD recorders as well as for inserting signal processors, such as EQ's, Reverbs, Spatial Enhancers / Dynamic Processors, Noise Reduction units, Special Effects units, Time Delays, etc) Dubbing can be used with CDR (CD recorders) units)
- 'Effects Record' function, for imprinting to recordings
- EQ defeat / bypass
- Dual, front mounted 1/4" instrument jack for mics, guitars or keyboards adding input abilities for 2 channels w/ Level pots for each of these channels.
- One un-switched AC convenience jack located on the back rated at 100 Watts

 Original Sansui RG-707 Specs:
 
 # Channels: 2 (stereo)
 # Bands: 7
# Cut / Boost dB's: 12 (most do only 10 dB)
Input Sensitivity / Impedance: Source / Tape; 150mV / 47kΩ @ 1kHz
Mic; 0.5mV / 10kΩ @ 1kHz
Guitar; 7.0mV / 100kΩ @ 1kHz
 Output Sensitivity / Impedance: 150mV / 47kΩ @ 1kHz
Frequency Response of electronics: 20Hz-20kHz
Signal to Noise: 70dB
THD: 0.05%
Channel Separation: 50dB @ 1kHz
 Echo characteristics: Time = 0-3 Sec. / Delay = 0-50msec

It allows fade between Source / Channel 1 and Channel 2, add 'Echo' effect to source or channel 1 / 2 and more. There are front mounted 1/4" instrument jacks for mics, guitars, keyboards, etc with a separate variable level control. The 40mm graphic EQ faders are +- 12 db range. There is a separate recording output so you can listen to "effected" audio with out affecting your recording.
Again, great 'multi-use' signal process for the musician's stereo system or project 'home studio'. Great for adding your vocals, keys, guitar etc to your stereo system (be careful with your 'home audio type' speakers doing that).
This unit is in immaculate condition. We have completely gone through it cleaning all and installing new display lamps. Unit looks new and works great! Measures 17" wide x 8.75" deep x 3.5" tall and weighs 6 lbs unpacked. Includes our standard 30 day limited warranty.

We strongly suggest that purchasers of our EQ's with pink noise generators and spectrum analyzers call us for advice on proper and full use of these types of equipment. We will be more than happy to walk you through the connection, set-up and use of this and any gear we sell. An EQ / Pink Noise Generator / Spectrum Analyzer is one of the greatest "tools" available for any stereo system, but only if utilized correctly.
