I know there's a problem with tubes in these amps getting too hot for the circuit boards, and I read a post where someone recommended touching each component with a chopstick to see if I could find a bad solder buzz. I get the noise at R35, but it looks like a witch to try to work on the board. I'm an engineer, familiar with working on electronics, but by no means a pro. Is this something I can fix? I might try the WD40 potentiometer cleaner first, just in case. I'll add a link to Imgur below if it's allowed.
