Ive had my maz jr nr head and zbest cab for about 4 months now and I absolutely love it. But at church service one time, i was about to start a heavy rock tune when i glanced over and saw that my amp light was off. I Ran over there and did everything i could for about a minute. I turned it off and back on... I even switched power sockets to no avail. Luckily, it randomly came back on and it played perfectly for the rest of the set. Ive been using it for about 2 months since the problem and it hasnt happened again.
Has anyone else had this kind of problem? My reissue twin did it once and it also has never done it again. The amp had been on for about 3 hours, but only 25min of each hour was playtime, the rest it just sat there on idle.... but not on standby. I checked the grill and it was not unsually hot so i doubt there was any overheating. Any ideas?

There's no automatic overheating shut down on a tube amp. Possibly a fuse problem or fuse holder problem. If it was me I'd replace the fuses and then wait and see if it ever happens again. As a backup you could always plug into the PA. With a good compressor and o/d pedal you can get by well enough that the audience won't notice a real problem.

If the above comments don't help, here's what I'd do:
First, look at the rectifier tube next time this happens. If it's not glowing, give it a wiggle; and, if that doesn't work put a bit of pressure on it pushing it up into the socket. If it fires up there's your issue - loose socket or faulty tube. Either replace the tube or reset the socket tension (might simply have a prong not making good contact).
Mine's going in the shop for either a new socket or a tweak. I've done what I can and it's not improved. Started doing the same thing described above (initially thought it was a power brown-out also as mentioned above) and when I wiggled the rec tube the amp fired back up. Has happened a couple times at different venues remedied by the same action, so it's off to the shop...embarassing when it happens onstage during a show (especially backing an artist...yeesh).

we did a gig in a bar and the other guitarist's twin reverb would just not work, if I remember correctly he had a pilot light but no sound, we took it into the shop and the tech told us "it works just fine" nothing wrong with it. Here it was the bar's electrical supply to the stage area was just one circuit and with all the stuff we had plugged in to it there just was'nt enough power left to fire up the twin, maybe that is what happened to you.

I reread the original post. He said he had no pilot light. That could only be a power problem related to the fuse or switch, if the A/C socket was okay.

Awesome, thanks to all for the replies. I hope it wont happen again, but if it does, I know what to look for. Thanks again ;D
