We were setting up for last night's gig and I plugged the SR into a power strip and powered up. The pilot light was lit for a couple seconds (3) until it went out. I had extra fuses and tubes and thought the outlet might have been a problem. I changed it and the fuse and it happend again, and again.
Fooling with replacing tubes is the last thing I want to do in that situation, especially on a stage so cramped there's no room to turn the head around to look inside. Time passes pretty fast when the house is full and you have this kind of problem.
Fortunately the gig was only about 20 minutes from home and I went to grab my trusty Vibrolux which never sounded so good and is now officially off the market. The club owner was cool about it and we shifted our time back an hour.
I just learned the Recto tube solution for the 1/2 amp fuse last week. Replacing the Recto tube was also the solution to the 3 amp fuse problem. This is apparently a multifunctional tube. I have replaced it with a solid state rectifier. Hopefully this will prove more reliable.

"This is apparently a multifunctional tube."
The rectifier takes the ac power from the wall and turns it into dc for your tubes. The 3 amp fuse is your ac fuse and the 1/2 amp fuse is your dc fuse. Depending on exactly what fails inside the rectifier it could cause either fuse to blow. Bad output tubes can also cause the 1/2 amp to blow, and sketchy wall power can cause the 3 amp to blow. These are the most common problems YMMV.
