I've had this amp for 12 years and it's been good until recently. I never cared for the drive channel, but the clean was very nice. Anyway, it's been giving me a hard time. I just replaced all 6 power transistors. I knew at least one of them was bad. Now it blows the fuse. I'm guessing I did something wrong, but I don't know what, and I don't really feel like trying to figure it out as I think I may have damaged the board itself. After coming across this site, I'm starting to think it may be time to scrap the board and try to re-use the larger components to build something new.

The amp is rated at 105w into 8ohm and 160w into 4ohm, so I'm looking to build a power amp that will match or nearly match that output reusing the old power transformer. According to the schematic, the power supply puts out +/- 45vdc and +/- 16vdc. I'm very noob with this stuff, so I don't what would work well with that, besides the old power amp, which uses 3 TIP142 and 3 TIP147.
