Hi All,
I'm pretty sure I need to replace both STK-0039s in a beautiful SA-300 I recently acquired. All I get is buzzing on headphones or speakers, but the audio from the tape out sounds great.
I started to suspect the STKs and sure enough the voltages on several of the pins appear to indicate shorts opening the -36v to pins 1, 3 and 8.
I would love to upgrade them using rcs16's design, but I don't know the first thing about submitting designs to a PCB manufacturer and probably wouldn't be able to answer any questions they have. Does anyone have any extra boards or know where I can get one from a place that's made these before?
Thanks!
