C3023 is not in the parts list. The 3000 series parts are on the Y/C pcb.
That is difficult to work on so I usually just pulled one from the boneyard
when I needed one. When I HAD to work on one, I mounted that board on the
bottom of the main board, using 1 inch solid wire jumpers, so I could get at
the parts with test probes. I had lots of bad boards for parts so if one IC
wasnt working properly, which I could tell from bias and waveform
measurements, I could just pull a bunch from the bad boards until one
worked.
I dont recall capacitor problems on that board, but they are old enough now
for the electrolytics to be reaching the end of their life.
