Hi guys! I'm new here and hope anyone can help me with this!
I got this preamp as a present from a colleague. But I recognized there is a low frequency humming (around 100 Hz) when I turn on the effects section. He said he never heard this before but he also didn't use it for a long time.
As I don't have any skills in electricity/tube stuff I can't really work on the inside of the preamp. But I asked myself if it could be the tube which is not working anymore and then produce such a humming?
I also recognized that when I press on a certain location on the top of the amp or if I hold it in the hands and move it around the humming disappears for a few seconds but always comes back then.
