We've been 'sitting' on this deck along with a few other 'difficult / performance critical' decks for a few years now, waiting until we had a technician with sufficient skills to 'do them justice' and realize their top potential performance. Sure we have been able to do more 'bread-n-butter' decks for years, such as Akai 150 / 210 / 1700 / 1800 / 4000 series, Sony TC-100, 300 & 300 series, Teac A-4010 / 6010 series, Pioneer RT-707's and 909's (yes, great looking and darn good performing decks, but I hate to 'burst your bubble', but while they have proven to be a 'durable' design 30 years after they were discontinued, they're no where near the best performing decks as R2R's go, sorry) and others, but chose not to 'tackle' these. Well, now by a stroke of luck, we have 'him'. Our 'new to us' technician is able to really 'do justice' to decks such as this. Yes, he's expensive and it's time consuming, but AS ALWAYS, we are striving for TOP quality and not for 'cheap'. If you want 'cheap' there are plenty of 'as found' decks out there to 'roll the dice' on. Our new technician spent much of the 1970's managing the service department of the famous Pacific Stereo chain, then on to their 'Recycle Audio' division. Heck, the guy even 'co-invented' the optical mouse (you're probably using one right now). He's our guy to restore decks such as this!
Our technician has completely gone through and 'Certified' this unit. We have completely and extensively gone through the mechanicals and electronics of this unit. Entire transport was disassembled down to the chassis, and every mechanical part was cleaned, re-lubed and reassembled. Flywheel was removed, cleaned and reinstalled with silicone lube on flywheel thrust plate bearing. The capstan was burnished, heads have been cleaned and de-magnetized as well as the entire transport. Again, the entire transport assembly was painstakingly disassembled, cleaned and re-lubed as well as the always at issue, 'Pinch Roller swing arm' assembly. 'Auto-Stop' mechanism disassembled and re-lubed with fresh 300,000 silicon damping fluid. Also hub brakes have been cleaned, re-lubed, and adjusted on fast wind modes also. Rewind 'back tension' adjusted. Motor 'start / run' capacitors checked. Voltage selector set for correct North American AC current at 117-120VAC. All internal pots / controls cleaned in both the playback amplifier, record amplifiers and the built-in 'audio' amp and tested for noise-free function. New VU meter and direction indicator illumination lamps / bulbs installed. Both spindles were completely disassembled, cleaned and had their bearings / bushings cleaned and re-lubed and are in perfect alignment. Main Drive and counter belts replaced for trouble-free service. Rubber pinch roller was removed, cleaned & reconditioned. We also adjusted the reel table heights. Tape heads and entire transports demagnetized.
Heads in Like New shape as well, with many hundreds of hours of performance left in them and head alignment / azimuth has been checked for peak performance on both play and record heads with factory STL 30Hz, 50Hz, 100Hz, 200Hz, 500Hz, 1k, 2.5k, 5k, 7.5k, 10k, 12k & 15k as well as 700Hz 'reference' tones thru an oscilloscope and with a dBm meter and were charted (we have the full L&R, Forward and Reverse, Normal and 'High Bias' results charted and available to the purchaser, but too much typing to display here as it's over 100 documented results). Suffice to say, this unit Plays and Records INCREDIBLY WELL starting with the following results using 'High-Bias' tape, from 200Hz with -1dB & from 0dB to +1dB 1k to 15kHz!!! We further tested it at -1.5dB @ 20kHz and -5dB at 35kHz. YES, you read that right! All the way to 35kHz. AND the above results were referenced at '0' dB on the meters, not the typical and EASY -20dB!
Both PB output levels and VU meters playback internally adjusted for even response. Floor noise measured at 0.4mVAC at idle and 1.7mVAC with blank tape in play mode. (Akai GX-260D's do have a DC surge / thump at turn-on, by design, so keep the volume on your amp / receiver down or off, or speakers 'Off' during power-up sequence.)
We really put them through the paces, testing both with well mixed, recently recorded CD material and CD recorded / factory test tones looking for correct head Azimuth and speed accuracy). Pinch roller and heads all in GREAT condition. Speed tested / checked to 98.4% accuracy utilizing 'Institute of High Fidelity' test tape. Following electro/mechanical restoration, unit received a cosmetic cleaning / detailing. There are a couple of chips to the side panel Formica, but nothing too distracting (see above photos). Overall looks fine.
Entire unit looks, works and sounds GREAT!
  (Total time investment in refurb / testing ~ 16+ hours). Pinch roller and heads all in GREAT condition!!!

GREAT performing Akai GX-260D 1/4" Open Reel stereo tape deck! Great for all-around Playback and especially recording of reels up to 7" in diameter. This deck has some very 'sonic specific' features, and while it would make a great deck for burning your tapes to CD or Hard Drive or for a 'media transfer business', we hope it will go to someone who will utilize and appreciate it's incredible recording capabilities. Some of the aspects that make it 'stand above the crowd' for recording, “The core of GX heads is comprised of a single crystallized element “single crystal ferrite” which has proved far superior to ‘poly-ferrite’ in that there are no minute ‘composite particles’ to eventually separate and cause head gap damage (wear). This is why Akai heads are famously said to ‘NOT WEAR OUT’.  

Center Capstan Drive – Most Auto Reverse decks, (and frankly, most ‘single direction decks’) place the PR/Capstan drive assembly asymmetrically. This creates ‘un-even’ drag and friction on the tape as it travels it’s path. One the GX-260D, the PR / Cap is situated symmetrically in the center of identical head clusters, with an even amount of flanking contact points. This greatly reduces tape friction, which not only ensure identical performance in both directions, but contributes greatly to the models incredibly low ‘Wow & Flutter’ (check the specs @ 0.06%!).
Also, as the heads are stationary, normal ‘head misalignment’ issues common with many ‘auto-reverse’ decks are not an issue on the GX-260D.
As a further testament to the quality of Akai’s motors, Akai was originally a manufacturer of motors in Japan before entering the 'tape deck' business. They had the ‘motor thing’ down!"

We also adjusted the reel table heights.  Tape heads and entire transports demagnetized.
Heads in Like New shape as well, with many hundreds of hours of performance left in them and head alignment / azimuth has been checked for peak performance on both play and record heads with factory STL 30Hz, 50Hz, 100Hz, 250Hz, 500Hz, 1k, 2.5k, 5k, 7.5k, 10k, 12k & 15k as well as 700Hz 'reference' tones thru an oscilloscope and with a dBm meter and were charted (we have the full L&R, Forward and Reverse, Normal and 'High Bias' results charted and available to the purchaser, but too much typing to display here as it's over 100 documented results). Suffice to say, this unit Plays and Records INCREDIBLY WELL starting at 30Hz with 0dB & -1dB from 1k to 15kHz!!! Both PB output levels and VU meters playback internally adjusted for even response. Floor noise measured at 0.1mVAC at idle and 1.5mVAC with blank tape in play mode. (Akai GX-260D's do have a DC surge / thump at turn-on, by design, so keep the volume on your amp / receiver down or off, or speakers 'Off' during power-up sequence.)
We really put them through the paces, testing both with well mixed, recently recorded CD material and CD recorded / factory test tones looking for correct head Azimuth and speed accuracy). Pinch roller and heads all in GREAT condition. Speed tested / checked to 98.5% accuracy utilizing 'Institute of High Fidelity' test tape. Following electro/mechanical restoration, unit received a cosmetic cleaning / detailing. No cosmetic issue to speak of. Looks near new. Side panels have 'crisp' corners and edges. No scuffs, scratches or anything work mentioning.....
  (Total time investment in refurb / testing ~ 14+ hours). Pinch roller and heads all in GREAT condition!!!
