awesome!~
i'd be very keen to find out more.
Mine was dead until i replaced a couple of power transistors in the +/-
5V stage that were buggered, and had been poorly messed with by a
previous owner.
I bought mine for $10 in a carpark junk sale, and took it home,
managed to get the midi control side going so now i can control my
other gear with the poly,
all of the patches etc can be edited stored etc, and i managed to
reload factory settings too, but no sound out.
It looked like the clock and everything was performing properly but no
tone out of the tone generator.
Soldering is easy for me, so if you can point me to the correct
component, i should be able to make it happy again, and that would be
awesome!
thanks again for your info so far.
