I have a vintage Lab Series L5 (solid state) that I've had for about a year and a half. When I got it, everything worked fine and the volume was so loud I could barely turn it up to 2-3.
However, a couple of months ago while I was playing I noticed a brief moment where the output power/volume seemed to fade a bit but then came back. When I turned the amp off, there was a very loud pop that came through the speakers. Not your typical turning-the-amp-off pop, but a much louder unpleasant pop that almost hurt my ears.
I decided not to turn it on again and was going to take it to my local amp tech but found out he unfortunately passed away unexpectedly, so that's no longer an option. I had some time to kill today and decided I'd try turning the amp on again just to see what it would do, and I definitely noticed an issue.
As soon as I turned it on, the channel volume and master volume were both turned to zero but a decently loud crackling/fizzy/radio-static type sound came through the speakers for a good 5 or so seconds then faded out to silence. After that, I could play through the amp and all of the functions were fine, but the overall volume/power output was noticeably lower than I'm used to with the amp. Previously 2-3 would be way too loud, but today I had it on around 3.5 and it wasn't loud at all.
Just wondering if anyone with more experience recognizes the possible issues that could be related to the symptoms I've encountered? Thanks in advance
