I bought Grawk's Toaster MPX3 a few years ago and it has been working ok however, it was damaged during shipping so it has had a quiet hum in one channel and a slightly broken spst switch since I bought it. With all the recent talk of the Singlepower disaster, I was wondering how much you guys think it would cost to fix the described problems, give the amp a once over, and re-case the amp in a new case. Do you think it'll be worth it? I like the sound but I have opened it up before and the star-grounding makes the wires inside look like a rat's nest. I have no experience with tube amps so I was thinking of sending it to an experienced DIY'er. Any advice would be appreciated.
