Literally babied. I never took this amp out for more than 3 gigs. and they themselves were in smoke free enviroments. Ill retube before shipping with stock mesa 6l6's. If anyone is willing or knows anyone please comment or send a PM. I played my friends road king and fell in love with the yellow channel. Plus it sounds good with some channels on the vaccume setting versus the Silicone setting. Id be willing to throw in the dual rec with cash.
