Tweaker 15 cutting out while playing

[currynoodles]

I have a 4 month old Tweaker 15 which I got recently from Singapore. I've been having issues where the amp is randomly cutting out while I'm playing and comes back on after a few moments. When it's cuts out, you can still hear sounds coming out from the amp, only that's really really soft.

Is it a tube issue? (I have a full set of tubes ready in hand to replace the stock ones if they are), or is it something more serious?

Tubes are ALWAYS suspect in this kind of thing. I'd try the power tubes first. Could maybe be fuses, or a short of some kind, but my bet is tubes.

Tubes would seem to be the likey culprit and since there are only 2 type of tubes (12ax7 & 6L6) it could just be a matter of trial and error swapping them out one at a time. Won't be a fuse tho as they have only 2 states, working or blown
