FInally figured out problem with my amp. Woo-Hoo!

I have a Peavy Delta Blues, 2X10, 30 watts. Real solid, cheap in cost only, tube amp. BUT i had problems initially after about 2 or 3 months. I was getting this static and unwanted disturbance while idle. So i went out and got new power tubes. No. the problem is still there. WTF? then came the new 12AX7 pre-amp tubes. problem solved. It's quiet as church mouse and new tubes all round sound fucking great. i love tube amps!

you do need to plug it in in order for it to work, you know.

Did you get your amp rebiased when you put the new powertubes in? Otherwise your powertubes could have a short life expectancy.

well its self biasing, or cathode biased, so it doesn't need it. and i'm gladder for it. i have other amps that need rebiasing like my old fender deluxe, but never did that..probably should.

Lucky! My Bassman has to be taken to a tech when I get tubes changed

My amp has a really annoying whistling noise that rings when I play with a clean lead. It's on a certain frequency that really invades my ears and makes playing undoable. Pissssses me off.

Sounds like a bad preamp tube.

It's only a 25 watt. I'm saving for a new one anywayzzz.
