Woundup

Are your amps still well? Ive had one of these amps for about a year and have a similar issue only present with the B Channel after the amp has been on for a period of time (I assume its heat related). My tech is pretty hailed where I live (in the US) and has at this point, after 3 visits, re-soldered bad connections on the preamp board, swapped a couple pots, and replaced all the power tubes. The problem is still not solved. I brought up the crappy bias sensing resistors when I first brought it into the shop but he was adamant that couldn’t be the issue because he doesnt use the built in bias input. It seems to be heat and not vibration related as playing with the amp away from the cab results in the same noises. It also has not once happened with the A Channel, which makes it all the more confusing. Would love to know if yours are still going strong and if anyone else here might have good advice for me, I love this amp when its working and would really like to keep it.
