Guys,
I blew a few fuses a couple months ago in my Lonestar classic. I retubed everything (with JJs) and it seemed to work fine for another two months. Early this week, I turned the amp on and it just died. The fuse was blown with excessive 'splatter'. (Earlier when the fuse blew, it was just a few of the windings that had burnt). I see no visible or smellable damage to the amp.
Today, I pulled ALL of the tubes, put the amp into standby mode, and put it in Diode rectifier mode. Turned it on...heard a quick hum...and fuse immediately blew.
Please confirm my suspicion that one of the transformers is bad, the rectifier circuit is bad, or something is being shorted. The amp is far out of warrantee, and I'd like to get this fixed ASAP...any suggestions??
Thank you
