Hello! I'm new here... sorry for being ignorant and newbie
I have an old Johnson Warrior 15 guitar amp that does not output my guitar sound. Instead, when I turn it on, it makes ever lasting oscillations (boop boop boop boop boop...). I heard the right term is "motor-boating" but I'm not sure. Anyways, it makes no other sound but the (boop boop..) when I plug in my guitar.
It's a solid state amp, 15w. I tried looking for schematics online but couldn't find anything. I tested the speaker itself and it works just fine. Another peculiar thing is that if I plug headphones to the headphones jack, I can here my guitar in my headphones. Another thing is that when I bypassed the transformer and connected DC current, it still occured, though the sound changed a bit.
Any ideas?
I'll provide more information if needed
