Josh, thanks!JMPGuitars wrote: ↑Fri 03/26/21 5:54 pmThere's your first problem. JJs in general have become mediocre, but their EL84 tubes are just trash.
That may not be the source of the problem, but very well could be. This is an example of bad EL84 JJs I posted 7 years ago: https://www.youtube.com/watch?v=21G6TkukwY8
I typically bought tubes in bulk, and returned all of the JJs at the time. There wasn't a single pair that didn't have issues out of the lot.
While you're waiting for new tubes, you might want to unplug the amp, remove all the tubes and check for shorts between all the tube socket pins and such. Inspect the amp visually too, with a magnifying glass.
Thanks,
Josh
Will triple check for shorts, and with a magnifying glass.
Any suggestions for EL84s?
