oh Bob you are such a tease! :) no but ... i am deeply grateful for your help. i am in here way over my head... i was hoping that if i did everything 'by the book' that i would be able to get it to work. it doesnt seem like a simple circuit to me... ive never worked on anything with a microprocessor before. when i did my undergrad in physics we just calculated far far simpler LCR circuits etc ... apart from that its just been 'hobbyist' type soldering jobs... but i do not want to be overly dependent on anyone here.... of course i want to encourage people to be helpful and not be a drain on people so i get that. but yeah i think thats the right response... you have to encourage people to learn what they do not understand! and transistors and ICs have always been a real weak spot for me... i feel a bit lost when it comes to such things...

Don’t go replacing all the resistors because of unusual capacitance
readings if you are doing the readings with the resistors soldered to the board.
In fact don’t go replacing them at all. That’s a bit like somebody who decides
to “recap” their old synth just because the caps are old. Too much room for
error and further damage there, when there is nothing likely to be wrong with
them. Sometimes it helps to post some hi-res photos of your new board. There are
enough people here who have built them that might be able to spot something
obvious that you missed.

so ill try to take over from here i guess...
incidentally... i remember putting in that zener and wondering how on earth
one can distinguish them from 1N4148 diodes... they are identical in almost
every way... so i just take it on faith that the zeners i was sent were not
mixed up for 1N4148s by the seller! but who knows. my next step is to replace
ALL the resistors for ones from another supplier since i checked them for
capacitance and they have unusual properties in that regard... (a head
scratcher)
