Uh oh. Here's the situation:
I got one from a shop here in brooklyn for $200. It was working fine for about 3 weeks of 3 rehearsals per week, getting signal from a coliseum lead whose volume was at 8. Input Sensitivity on the Slave was always all the way up. I took it on a 3-stop weekend tour and at the third show, the VU meter wouldn't light up. Power switch glowed red, though.
When I got back, I opened it up; the fuses were burnt. I replaced them with the same (25A 32V Fast) that were inside and fired it up again, hooked up to a 4ohm cab and no line in. After about 1 second of a loud humming noise, it burnt the fuses. Same thing happened with the front switch on Audio rather than 117, and with the sensitivity off.
Is this worth fixing?
