I use my Maz for a house gig at The Bowery in Myrtle Beach, SC. WE play 5 hours straight a night in the summer time. Now that the tourist season is over, we play on the weekends but we still practice a few night a week. We practiced tonight and after about 4 hours of solid rocking, we cut it off. I reached to switch my amp off (212 combo version) and noticed the face plate was burning hot. Like so hot I couldn't hold my finger on it for more than a second.
Has anyone else noticed their amp getting this hot? Should I be worried?

Does your amp have a fan and, if so, do you know if it is functioning properly?

Is the power at the venue OK? Sometimes, if the current coming out of the wall is too low it can heat up a power transformer.

Never noticed that with my 38 head; it gets hot but not HOTTTTT! The head has a bottom-mounted chassis that vents through the top of the cab. The 212 combo would have the inverted top-mounted chassis and unless it has a fan it could get pretty hot I would imagine.

Makes perfect sense, so it should have a fan? Likely. I'd say most of Doc's amps these days in that configuration have a fan. Some of the older models may not have them.

I have a Maz Sr reverb 1x12 combo and yes mine gets very hot like that too. Both face plates and switches hot to the touch etc. There are more tubes with the reverb model, so 10 tubes total fairly enclosed in the cab without the ability to vent out of the top like a head cab as mentioned. Actually I just picked up a head cab and I am going to convert the amp. The main reason for the weight of the 67 lb 1x12 cab, but another reason is the heat factor and better ventilation in a head cab. But agree, a fan drawing the hot air out of the cab should help a lot.

Should I see about having a fan installed? I've never heard of a Z coming with a fan from the factory but, I could be wrong.

I suspect your situation is exaggerated by using the amp for 5 to 6 hours at a time. I would certainly check to see if the Z shop would install a fan for you.

I have to ask: if this is the normal amount of time it runs during a nightly gig all summer, and you never had this issue before - something's changed. Any chance it has fan, and it's stopped working? At any rate, if it's too hot to touch, it should probably get a checkup...

I agree, and anyway 5 - 6 hours shouldn't be an issue at all, particularly for an amp as well build as a Z. Years ago when I was a pro player based in Germany we used to play that length of time 6 or 7 nights a week; I never had a problem, and I used a Peavey!
