I've double checked and I'm running a cable from the 8 ohm output on my amp to the mono 8 ohm input on my 2x12 cab.

All my power tubes are definitely glowing bright so if there is a problem it's in my preamp tubes.

Anyways, I'm still trying to figure out how I blew a fuse. Like I said I plugged a new effects processor in the effects loop right before the amp went out. Could I have screwed anything up then? Does the loop level need to be on a certain setting?

I really appreciate all your help
