My Conrad Johnson MV 50 eats tubes just like yours

Yep, blue flame, POP!, and there goes another tube. The problem is not in the tubes but in the circuitry needing some repair or adjustment. You might check if the tube that dies is always in the same location within the array of four. (With mine it is.) At least, that's what the people who sold me mine said. When I complained they said it had some noise and they couldn't fix it themselves, but they had sold it to me a little cheap because it needed some low-cost work. I called CJ and they said it was NOT likely to be tubes. They said that basically a tube is a tube -- "to an engineer, a tube is like a light bulb", meaning that audiophiles exaggerate their importance. I haven't sent it to the factory yet because I'm am debating whether to have an upgrade done at the same time. (I'm leaning toward NO, since I like the sound now so leave well enough alone!) There is a guy in Charlottesville VA who offered to work on my CJ -- he seems pretty trustworthy. I will provide name and number if you ask. But you might also send it back to the factory or go to an independent repair shop run by someone over 50. And don't buy any more tubes!!!!!!!! (til you get it fixed.)
