Had to pull my ad as I found some unknown problems. I was thinking of keeping it anyway - forced my hands on this one.
I Want to see if others have experienced these before I begin troubleshooting.
The mute circuit isn’t muting 100% - there’s still sound passing ever so slightly to the speakers. In 98 was this expected performance or is there a bad LDR or a relay not operating as expected?
Channel 2 is cutting in and out ever so slightly on palm mutes and I do mean you have to have an ear to catch it - very fast but noticeable and completely out - not a volume drop. Could be tube related yes, but tubes usually either work or do not work in my experience. The tubes are of unknown age in the amp. I do plan on retubing soon. Possibly a bad socket connection?
Thanks ahead of time! I’ll pull the chassis and put it on my bench when I get a chance, still working on the Marshall.
