I took my music man to a gig and the fuse blew right when i turned it on. After I replaced it and tried playing it again all it makes is a loud hum. As of now, I'm pretty amateur at repairs but i've managed to teach myself a lot and rather learn to do stuff myself instead of relying and spending money on someone else. | ||

sorry for the 3rd post, but i just tried to turn it on again and it will have a loud hum for about 20 seconds and then just shut off all together. any recommendations? | ||

YUP-sounds like a trip to the doctor. Could be as simple as a cap gone t!ts up or a transformer took a dump. OR a bad tube. When it blows the fuse, does one tube light up real bright or arc? | ||

No both tubes work perfect until the whole thing goes off. I just replaced them a couple of months ago. | ||

Does it have a 12ax7 PI tube besides the power tubes? Does IT go bright or not show any light at all? It could be toast as well and overdrawing the filament voltage OR the mains. If not, you're going to have to go inside and start normal diagnostics. |
