Destroying a Super Lead

This past Sunday, the other guitarist in my band and I moved our equipment out to our new practice area. Here, I learned that there was something wrong with my amp. After a bit of investigation, I learned the fuse for the output section had blown.

Today I purchased 8 replacement fuses, but since I live 20 minutes away from our practice space, I won’t be able to get one in the amp until tomorrow night. I don’t know why the fuse blew, but I imagine it has something to do with the fact that I run the thing wide open with an attenuator across the output. 

The thing that bothers me is that I might be destroying my amp without realizing it and I really, really don’t want to do that. It’s a 1976 Marshall JMP mk II Super Lead, 1959 circuit. All the parts are original and with the exception of an XLR jack someone installed for a line out which had been removed from the circuit before I bought the amp, it’s pretty much exactly as it was built 40 years ago. 

The 1976 JMP isn’t incredibly expensive nor is it sought after, despite being vintage. Still, it means a lot to me and is the best sounding amp I’ve ever used. Unfortunately, I feel as though I’m bringing it closer and closer to death every time I fire it up. I’ve owned it for 8 months or so and it’s been reliable as all hell up to this point. Blowing a fuse isn’t a super serious issue until you start blowing them all the time. My thoughts turn toward replacing the output tubes, but until this weekend, I won’t know if they need to be replaced or not.

It would probably benefit me greatly to go ahead and order a matched quad of EL34s for when the time comes just so I’ll have them. However, this has got me wondering if maybe I should consider searching for a fuzz pedal that will give me the saturation character that my wide open amp has so I don’t have to keep running it in the red all the time. I’ve even considered buying a second JMP mkII or a 1959HW reissue to use instead, but I don’t know if the tone will be the same.

First things first, tomorrow I need to verify that the fuse was the only issue. I’ll trust things enough to get through our Thursday practice session, unless I blow a fuse that night in which case I’ll put a plan of attack together. Assuming all goes well, I’m going to test the tubes Saturday just to make sure they’re not close to death. One bad tube and I could destroy the output transformer, then goodbye vintage amp as I’ll have to replace it with a newer tranny; probably one that won’t sound anything like the original.

Regardless, I’m nervous and want to know the answer.
