I'm brand new to Boogies, and just bought a Mark III that arrived yesterday.
After it's been running for a while (45 minutes or so), it makes a loud pop, similar to what you might hear if there was a short in the guitar (it's not that, or the cord). It's occasional, and did not happen when the amp was just on, but not being played.
The previous owner said that he did not have the problem during a long gig two weeks ago.
My suspicion is that a tube didn't survive the trip.
The power tubes are new JJ 6L6s, but no telling how old the others are.
Does anyone follow the manual's instruction to use only Mesa tubes, or is the potential for improper bias a minor issue?
I'd welcome any comments or suggestions (other than sell the amp cheap).
Thanks.
