Hi Mike
Personally I'd just like to know something about the process in the KAS leading to that drift, anything in the FIFO or else in the encoding-decoding process?
Thx for your insight!

Hey, I almost forgot about this thread. I'm planning on posting some audio files soon. Kent Spong's tracks inspired me to do so. It's really cool to hear his work and how the CS80 responds to the replacement parts he selected!
What sort of problems are you having and what have you replaced in the machine that is having problems? I wouldn't even bother with any mods unless you have replaced all of the CMOS, Op-Amps, and electrolytics.
