Discussion about the Korg PolySix synthesizer

Well, I guess I goofed and something is wrong with my clone board.  Unfortunately, my PSU had a lead break from opening and closing the synth so I can't test any further until I fix the PSU and order the fuses. Can I sub a 2n3904 for the Q5 2SC945?  I dropped in another 367 board that I had lying around and everything worked as it should with the exception of a couple buttons because somebody spilled a drink on it years ago.  

Here's my question, is there anybody in the USA that would be interested in fixing my KLM-367 clone board if I mailed it to them?  It's probably something stupid but I don't have the time or the parts available to really test it.  The last time I powered it up, I couldn't get any of the preset buttons to work.  It seems that they were stuck on 1A.  The chord memory was stuck too.
