Marshall 8100 (Recapped/Upgraded) . It has been overhauled right before I bought it. I linked a video where the guy goes over it. It takes a few seconds longer than it should for the tube to warm up ( say a minute to 1 1/2 minutes). I believe it is the auto transformer getting weak. I have a new replacement auto transformer and will include it with the sale. Only played it a couple hours since purchasing it. Will trade for a Fender MIM/ or better strat or tele in good condition Or a nice Epiphone les paul/ firebird.
