WOW. I can hardly believe it - everyone (who I am incidentally VERY thankful to for their patience) will be greatly relieved to know that I think i've LICKED my problem.

How? On a weird HUNCH - and thanks to Roman and Bob's suggestion - I noticed that my D2 (the zener diode in question) was measuring with a MUCH higher passive resistance than the stock D2 zener on my original board (around 12 Megohm - compared to close to 10K on the original for the same polarity) - so after reading about shunting etc and how zeners typically need a high value resistor (like the 10K next to it) to help them function better in such circuits - that something was off. I was wondering how the HECK the zener i was using would work - assuming (perhaps wrongly) that the current would rather flow through the resistor.

Okay- sorry - i'm  being too verbose. But anyway- I swapped in the OLD D2 from my old polysix board - and NOW it sort of works - it's not perfect... I still have program patch 4 and 5 eternally lit... but other buttons and functions now seem to work. I haven't tried to see if I have audio yet.... but this is a HUGE leap forward to me... so again - thanks SO MUCH you guys for helping... !
