hey all, I reach out once more to hopefully get some more information regarding my monopoly. The original problem of VCO4 not being able to tune properly has not gotten much better.  There is about one octave that is in tune and stable but...  We are now at the point of the lower and higher notes not scaling properly.  If the lower notes are calibrated than the high notes are off and vice versa for calibrating the higher notes.  He has replaced the VCO trimmers, some resistors along the way; but is now stuck.  Which he has a hard time admitting to me.  He is not circling around the ssm2033.  But I have had numerous people (including some of you) suggest that the SSM2033 should be the absolute last resort and does not normally create tuning/stability/scaling problems.

I beg of you to give me any hints or easter eggs that I can relay to him in order to make any grounds.  I just can't imagine that this issue is so complicated to diagnose.  The next move would be to swap the VCO4 SSM2033 with another voice to see if the problems travels with the chip.

He has repeatedly stated that he doesn't believe the problem to lie within capacitors... I am not sure if this is valid, as I find myself in this position because of a short that blew the fuses. Wouldn't it be possible that the short damaged some caps along the way  

I refuse to believe that this is a last resort.  I can find the SSM2033 on eBay through our analogsynthdoctor friend... Which he claims that the thermistor is actually just a metal film 175ohm resistor... Is this true Can anyone corroborate this information

I have reached out to Ko and am waiting to hear back. He says that he can have it fixed for a flat fee of 200 plus shipping which seems more than reasonable considering the amount of money I am racking up with almost experimental diagnosis with my current tech.  Which I probably should have done in the first place...

Please help me out here guys.... I am desperate, and not going to let my beloved go down without a fight.

Thanks In Advance
