edgranholm said something in his second post, He said he had only turned on the amp once since finding it again,

Attention All Tube Amp Owners, if you have amps sitting around not being played, shoved back in the closet or back at Grandma's house, About 2 or 3 times a year you need to turn on the amp, and play it for a few hours, this will keep your filter caps formed and in good shape, Ed's amp is probaly suffering the effects of old age as much as anything else, but your new amps will age prematurely if a charge isn't kept up on those capacitors, transistor amp owners disreguard, just kick your amp real hard occassionly
