I've got a VIBROLUX reissue. Amp is great. Problem is, after a set or two of playing, the power light goes off. Amp still works fine, just the light goes off. If I power down, then turn it back on, it comes back on and works fine. Again, the amp never stops playing or (seemingly) has any power or tone loss.

Anyone ever experience this?

Is the amp trying to tell me something, or do I just need a new bulb, or have gremlins taken over?

Thanks.

My Model T does that for some reason too. I've tried putting in new lamp bulbs but to no avail.

FWIW - The available schems I find for the vibrolux show the power-lamp wired in parallel with the tube heaters. That would mean the lamp dimming out would mean the heaters also dim out. But you don't hear any difference in sound so I'd suggest trying a new lamp SOCKET - it might be getting warm and shifting ever so slightly as to break contact.
