Cheapest tube amp in terms of initial as well as maintenance cost.

Back when I bought it used it cost me mere $200, but that ain't the only thing cheap about this bad boy. Even its 6N2P-EV, and Sovtek 5881/6L6WGC tubes cost dirt cheap. The amp is in damn fine condition but the rat tolex kinda stinks. As for the wiring, that's the most surprising part about this amp, it's handwired. I never expected such a cheap ratty looking amp to be handwired. As for its sound, it sounds very similar to a JCM800. It has a bit more gain but other than that it sounds more or less same as a JCM800.
