Did you know?
MCS was marketed in the US, by JCPenney's in the 1970's and '80's and has generally proved to be solidly designed and built gear in the long run (not so much gear past early 1980's). Most MCS (Modular Component Systems) equipment was built by either Matsushita (parent company of Panasonic (founded 1918) and Technics (introduced 1965) or NEC (established 1898-99, originally known as Nippon Electric Company). Both VERY well respected, electronics industry giants. Most of the MCS stereo receivers and amplifiers prove to be fine performers once 'Certified' by a qualified technician. There are a few 'exceptions' and when we encounter one, they don't even make it to the bench, but then, most brands, including Pioneer, Marantz, Sansui, Kenwood, Sony & Yamaha made a handful of 'exceptionally cheaply designed and built' models that we won't bother to refurbish / restore. When I sold either Technics or Panasonic gear new, I knew there was a VERY low chance of that unit coming back with an issue, over many of the other brands I might have had at my disposal. Needless to say, I am a fan of most gear built by Technics / Panasonic and have seen enough of it to know that if I had to place a 'blind-bet' on an 'as-found' unit either being in 'functioning condition' or being close to it, gear built by Matsushita (NEC as well) will be a 'safe bet'.

SOLD 10-2-12
SHIPPED TO GEORGIA 

Our technician has completely gone through and 'Certified' this unit. Everything was cleaned inside and out including all switches, controls and contacts. 'Stereo / Mono' switch replaced. Heat sink compound on all transistors and voltage regulators refreshed. Tuner string re-tensioned. We also aligned the tuner front-end for optimum AM & FM performance as older internal tuner components have always drifted on vintage gear over the years and this one had definitely drifted. All dial & meter lamps replaced with new bulbs for trouble-free service. All inputs tested and both side produces clean and even sine waves into static 8 & 4 ohm loads! No power supply hum of any kind. It's dead silent! All functions test fine. Following restoration procedures, the unit was run continuously at medium volume, as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 48 hours. Total restoration accomplished in about 6 hours.

SOLD 10-2-12
SHIPPED TO LOUISIANA

Our technician has completely gone through and 'Certified' this Realistic STA-235B. Everything was cleaned inside and out including all contacts, switches and controls. AM & FM tuner alignment checked and performed as necessary including Frequency centering, and model specific and Realistic exclusive 'Auto-Magic-Tuning' circuit (this is an amazing feature that I will explain later). Tuner front-end, FM muting circuit and MPX circuit adjusted for optimum performance. VERY GOOD TUNER! Generally AM reception in a stereo receiver is treated as an 'after thought', but the AM reception on this Realistic STA-235B, #...7708 is WAY above average. VERY GOOD TUNER! FM reception as well great and IMPECCABLY CLEAN!!! All dial & meter lamps replaced with new bulbs. Cleaned tuning capacitor for clarity. Amplifier outputs adjusted to eliminated crossover bumps on sine-waves. We also replaced both 1/4" front panel jacks with new, as well as the original fuse holder. We also painstakingly removed, disassembled, cleaned and burnished the power switch contacts, and added an 'in-rush' capacitor to extend the power switch life, as this unit does not come stock with one.
Entire unit detailed inside and out. All inputs tested and both side produces clean and even sine waves into static 8 & 4 ohm loads! No power supply hum of any kind. It's dead silent! All functions test fine. Following restoration procedures, the unit was run continuously at medium volume, as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 48 hours.

 Our technician has completely gone through and 'Certified' this unit. This Rotel RX-304 stereo receiver has had our complete bench service / refurbishment / detailing, including cleaning all switches, contacts, and controls cleaned for static free performance, complete cleaning inside and out. Even though all dial and meter lights were functioning fine, we proactively replaced them all with new units, for trouble-free service. Tuner checked and aligned as necessary, including adjusting 'pointer' accuracy. All inputs tested and both side produces clean and even sine waves into static 8 & 4 ohm loads! No power supply hum of any kind. It's dead silent! Unit looks and sounds great. Following restoration procedures, the unit was run continuously at medium volume, as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 48 hours into a 4 ohm load.
  
 
On our test bench, the internal amplifiers of this particular unit #...9205, produced 15 volts per channel @ 8 ohms for 28 watts and 12.9 volts @ 4 ohms for 41 watts per channel with 1 kHz input. (Sanken SI-1125HD Output power pack)
(AC draw at idle 0.027A tested. DC offset at outputs measured at -0.027 VDC L & -0.034 VDC R)

SOLD 6-12-13

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

ü  Everything was cleaned inside and out
including all contacts, switches, controls and I/O jacks.  

ü  Control Pot shafts re-sprung.
Internal and external fuses checked and replaced where necessary.  

ü  Bad driver board capacitors and transistors replaced.  

ü  Slightly leaky TO-3 output transistor replaced with
an exact and original transistor we had in our 'private stash'.  

ü  We also extensively aligned the tuner front-end,
as well as the 'MPX' circuit for optimum AM & FM performance
as older internal tuner components have always drifted
on vintage gear over the years. Generally AM reception
in a stereo receiver is treated as an 'after thought',
but the AM reception on this Rotel RX-803, #...7457 is pretty decent.
Great sounding FM tuner on this receiver. Very clean, punchy and musical following alignment.  

ü  All dial and meter bulbs replaced.  

ü  DC offset and driver board / output bias current set to correct values.  

ü  All inputs and functions tested, and both amplifiers produce
clean and even sine waves into static 8 & 4 ohm loads!
No power supply hum of any kind. It's dead silent! All functions test fine.

ü  Unit has been thoroughly detailed inside and out.

ü  Following restoration procedures,
the unit was run continuously at medium volume,
as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 72 hours and into a 4 Ohm Load!
Only cosmetic issues are a bit of minor wear to the face,
including a small blem to the silver plating (see above photos).

VECTOR RESEARCH VRX-9000 / VRX9000

 Circa 1978-'83
MIJ
SOLD 9/5/13
SHIPPED TO TEXAS


Our technician has completely gone through and 'Certified' this unit.
-
 
Everything was cleaned inside and out including all contacts, switches, controls and I/O jacks.  
-
We also aligned the tuner front-end for optimum AM & FM performance as older internal tuner components have always drifted on vintage gear over the years. Tuner digital readout is within 0.1Mhz of spec, meaning example '98.1' reads '98.2'.  
-
Battery backup compartment clean and corrosion free.  
-
Generally AM reception in a stereo receiver is treated as an 'after thought', but the AM reception on this Vector Research VRX-9000, #...4176 is WAY above average (frankly it's amazing). VERY GOOD TUNER! FM reception as well great and IMPECCABLY CLEAN!!!  
-
Power indicator meter lamps replaced.  
-
DC offset and driver board / output bias current set to correct values.  
-
Entire display / readout works perfectly.  
-
All inputs and functions tested, and both amplifiers produces clean and even sine waves into static 8 & 4 ohm loads! No power supply hum of any kind. It's dead silent! All functions test fine.  
-
Following restoration procedures, the unit was run continuously at medium volume, as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 72 hours.
  

 
  On our test bench, each internal amplifier of this Vector Research VRX-9000, #...4178 produced peak power of 30 volts per channel for 112 watts per channel @ 8 ohms and 25.5 volts @ 4 ohms for 162 watts per channel via discrete output devices. Idle current measured at 250mA. Bias current & DC offset / output adjusted to levels within spec. Floor noise measured at 3.3mVAC.
  ____________________________
 

VERY PUNCHY Vector Research VRX-900 Stereo Receiver designed in the tradition of the classic analog models, but with the convenience of a digital tuner. This is a very punchy and full sounding receiver (witness the 3dB 'headroom' spec). Very 'musical' sounding. Doesn't fall apart with larger speakers utilizing 15 inch drivers. This was their 'Top of the Line' model for that period with performance and specs to prove it. I actually sold this model when new, while working for a Vector Research dealer.
  Features include:

 
 
 - Quartz Locked, Digital Synthesized tuning (but still internally adjustable for technicians)
- 6 AM & 6 FM tuner presets
- A, B and A+B speaker selector
- Separate Bass, Mid & Treble with high quality de-tented controls
- Dual Analog 'VU' Power Meters with Dual Range Selector
- Dual tape deck monitors
  
(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® / 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)
- Bi-Directional Tape Dubbing
- Phono / Turntable input
- AUX Input (may also be used for Video / CD / DVD / VCR / DAT / MP3 / XM / SIRUS etc.)
- Variable "Loudness" control normally found on Yamaha units
