I won a bashed up Six Trak from eBay the other month and had quite a fun time repairing it. It was sold as partially working with no guarantees so I rolled the dice with a low offer and won. The description said that Voice 6 was bad and that it was not the CEM 3394. This had been replaced. When I finally had it working, the main problem turned out to be the battery was bad and the calibration data was corrupted. There was nothing wrong with any of the 3394's. A few 4000's series chips were bad. Sadly, the previous owner had read something on the net somewhere that stated that when a Six Trak voice is bad, one must replace the 3394. This is not always true. Bad advice. Don't replace any of the devices until the battery is changed and a full calibration is performed. A Six Trak will act like it has a bad 3394 if the calibration data is corrupt. A good test is to transplant voice chips from a working voice to non-working. Its likely the previous owner had pulled and replaced a perfectly working 3394 and pitched it out. In other news, I have Tauntek's OS Rev 12 installed and working perfectly. My Six Trak is #46 so its very early in production. Tauntek's OS Rev 14 did not work on this machine. The patch changes jumped uncontrollably. This may be due to a bad potentiometer on my particular machine. The problem is not present with Tauntek OS Rev 12. For posterity.
