Sov-Tech

Thank god for the Russians. What we previously thought was a bad vacuum tube turned out to be nothing more than a broken wire in the speaker jack. Soldering that back together put the Marshall JCM 900 back in operation, until it broke again about a week later. This time I noticed a purple glow in the back, and I thought, hey, that's kind of cool. It's not too obvious in this picture, at least compared to the one glowing the bright cherry red.

Taking off the back made it more obvious. A little research tells us that the purple glow is ionized air that has leaked into our vacuum, so it looks like we are going to need a set of power amplifier tubes after all.

Here's our set of new tubes from Old Town Music. Made by Svetlana. In Russia. Who'd a thunk we'd be buying electronics from the commies for an amplifier made in socialist Britain?
