Hello,
If it's posted in wrong subforum - my apology; admin please remove it to proper one
I have problem with power tube amp which has started about 10 day ago.
The amp after 10 min since it's on, starts 'farting' and buzzing, making distorted noise in both channels...very ugly and scary
it dissapears after about 40 min (within this 40 min it happen from time to time, and lasts for few sec)
Funny thing is when I stomp on the floor, it stops....like it was a cable issue, but it's not I checked it
Could it be a simple tube problem (amp is over 10 years old) ?
How to spot the issue if I am not a diy'er and doesn't have any tools except soldering iron (for making cables) ?
many thanks in advance
