I have a "pre-owned" Marshall TSL 1oo amp head (the former owner is a friend), and after playing through it for thirty minutes or so, the freaking thing blows the T1A fuse. I switch out the fuse - it repeats the destruction with the new fuse. I figured, maybe it's old tubes, so I spent 120 some-odd bucks to completely re-tube the thing (pre-amp AND power amp tubes). The new power tubes are matched, and correctly biased; The speakers are set on the correct impedance (8 Ohms for my 2 cabs) - and, after 30 or 40 minutes or so of playing, once again it blows the freaking T1A fuse. I can not figure out why the bloody thing keeps doing this.
My Peavey 6505+ head works fine and operates off the same power source. I would like to be able to shift to the Marshall sometimes, but at this rate I'd be mid-tune during a gig and the f'ing amp is just gonna drop out on me....
Anyone heard of this problem with a Marshall before? It's pissing me off. What the hell would cause the fuse to keep blowing? I'm beginning to think this particular Marshall head was just a major waste of money 'cause it's beginning to look like a real piece of sheeeeit.
