I loved my Classic 400. It's loaded with a bunch of EHX and a JJ preamp tubes, and some Winged C Svetlana KT88s. Sounded boobies until it died. It's sitting in our regional tube wizard's shop, waiting for some divine intervention. I'm pretty sure it has tried to kill him a few times. But, he's got a real nice track record and reputation for being thoroughly awesome. So if it never gets fixed, it just wasn't meant to be.
