Neotek Series 1E Console

Several months ago we acquired a 12-channel, vintage Neotek Series 1E console circa 1984. It once belonged to a university, which was sold to a guy who sold it to us.  When we dragged it into the studio this is what it looked like (from lousy iPhone camera):

The console was supposedly in non-working condition.  I was able to get the power supply working with a few replacement fuses, and once hooked up to the board it was powered on and functioning.  The power supply itself could definitely use a rebuild, but it does work.




The bigger problem with the board was that the wiring was all snipped off at the wall when it was originally removed, and no documentation was available to show where everything hooked up to.  If it had used typical XLR and 1/4" jacks on the back we would have been golden right from the start, but these units use ADC patch blocks, and without documentation you're pretty much up the creek without a paddle...
 






I started the process by ripping out all the wiring and saving it, since it was all perfectly good.  By the time I was left with empty patch blocks, I was ready to start the extremely time-consuming process of checking each block, one-by-one, to see where audio signal was coming from.  I'm not that savvy with schematics either; this part sucked!

Eventually, and with some help from the Neotek Mailing List I was able to find the ins and outs or each of the channels and stereo outputs.  Once i got that going,  I started painstaking process of cleaning the board, channel by channel...






Taking apart...






Look at how nasty these things were...
All panels removed and cleaned.







Putting it back together, looking much better...





12 channels later, 8 submix panels, and the stereo output section, this thing looked brand new.  At present time the only thing that is not working are the LED meters across the top, which is because of the 35V rail on the power supply and it really isn't a big deal.  But I took out my OCD on this beast and turned it around!  And most importantly, it sounds AWESOME :)
