Hi gang. I have an original Cyber Twin combo amp. It's worked great since I got it, and I use the S/PDIF for recording quite often. Recently, the sound has some high end distortion when signal is going through (meaning while I'm playing). Silence (like between notes) is unaffected, so it's not a constant hum or anything like that, just an effect on the signal being output. Otherwise the amp works fine. Has anyone heard of this problem? Thanks, J

The SPDIF output is shown on the left side of sheet 3 of the schematic:

It is transformer coupled. After the transformer, it disappears into the bowels of the amp and I lost track of it. If the transformer is not the problem, I have no clue what it would be and it would probably be difficult (read: expensive) to find the problem and fix it. Sorry.
