Hey all,
I have a PT-20 that I bought used about 2 1/2 years ago. Today I noticed that after 15 minutes or so of playing, the amp start making noise all of sudden. Basically hiss. Sounded like white noise. I turned off the amp and turn it right back. Noise was gone and then re-appeared about 15 minutes later. This time, I turned it off left it alone for about 20 minutes. Turned it back on and played for 30 minutes and heard no noise. This time, the only thing I thought I noticed was a slight volume change after 20 minutes. Sounded like it got a hair louder.
As I said, I bought it used and in truth, I haven't played it that much. I'm going to pull the tubes and clean the contacts. If that doesn't change anything, I'll change tubes, etc. Ultimately, I have a great local tech I can bring it to.
Just thought I'd post here in case anyone has had similar issues with this amp.
PS, other than being a used amp, it looks absolutely mint so I doubt it was abused by the previous owner. Looks totally stock as well.
Thanks!
Dave
