Discussion about the Korg PolySix synthesizer

TH1 is probably a thermistor, a temperature-dependent resistor.
Guessing it's there to help stabilize the LFO frequency as the 
temperature changes.   The transistor that it's hooked to will 
change a little with temp, so having the resistor change as well
sort of cancels that out.

You don't need to worry about the vias.   Only pc bds damaged 
by corrosion have issues with them.  

I am guessing that you don't have an oscilloscope, right?
Did you get a good 5V on the KLM-367 yet?

Good luck,

    Bob

       Bob - just  found a few components i missed (!!) -
 the TH1 (whatever that is.... oscillator??) - and on of the
 resistors (d'oh!)  - so that should help things. Still
 not working though - 
 
 question: " Do the vias all have to be
 filled/soldered??" 
 
 -
 I'd assumed not since they were (presumably plated
 through... but just in the off chance I somehow missed
 this.
 
 Thanks for all your
 help today by the way.
