Hello, first time poster here. A Studio 22+ came my way for a bargain price 18 months ago - the 5 pre amp tubes were replaced just before I collected it, and I replaced the power tubes (with a pair of Mesa EL84's) just over 6 months ago.
Yesterday, I changed channels (from rythm to lead I believe) and suddenly started getting a very loud popping noise, which then continued across both channels, and even with the amp on standby. This morning I put the old tubes back in....absolutely fine (albeit with a little more general noise on the clean channel than the newer tubes). Tried the new tubes again and got exactly the same loud continuous popping.
Band practice is this Saturday so relieved that putting the old tubes back in has sorted it for now - but is it fairly common for new tubes to fail after 6 months? (literally about 4 days after the Mesa guarantee has expired!).
As the old tubes have rectified the problem I'm assuming it is the new tubes and nothing in the amp that's causing it. Anyone else had similar issues using this (brilliant) amp?
