Discussion about the Korg PolySix synthesizer

Thanks,

I believe that this type of info should be shared all over the net. 
The Trident's schematics are very rare - took me weeks to get them;
however, here they are.

I got my Trident in disasterous condition, nothing worked, battery 
corrosion, bad chips, everything you may think of... Got it work 
finally after doing the refurbishment step by step. This is an 
incredible machine, one of the best ever made and definately Korg's 
best Polysynth.

Let us know how you proceed, also if you can take some pictues of the 
board it would help.
