I agree with Onhwy61 - Lee Marvin is the man. If he is in the mood for tubes, he heats up jeep windshields with a flamethrower, rolls them into bulbs, then sucks all the air out of them, and sticks his dogtags inside for getters. If he wants some solid state power, he chews up some KT88s in his mouth and spits them out at high temperature and pressure to make silicon for transistors. I do the same thing with money and things around my house that I don't suspect will be missed, and turn them into audio equipment of both varieties. Like Lee Marvin, I use whatever I am in the mood for at the time, and enjoy both.
