Hope someone can help, if not point me in the right direction, I apologise first off for using the forum to bum information, I'm new to all this amp talk and haven't a clue where to turn.
I bought a Bugera 333xl after reading probably 50/50 reviews for it, being my first all tube amp, i thought the price (£424.00 here in the UK) was reasonable so went for it.
I have been using it, say, every other day, probably a bit less in my front room, the amp hasn't seen past 8pm on the dials, yet today when i turned it on, the amp was warming up, as i was strumming with the volume increasing it went POP and everything went off!!! Lights and everything.
I am hoping it's something simple, but don't know where to start, if It's any help, it seemed to "POP" from left hand side of the amp, but can't be sure...
any help would be hugely welcomed.
The amp is only a couple of months old, but i bought it online and don't really want to end up sending it off to them(probably at my expense) only for them to hold onto it for weeks and weeks.
cheers everyone.

bugeras are known to have some reliability issues. go to the profile of a guy called BeerChurch for some help with them.

Sounds like a fuse - check them before you do anything.

you didn't let it warm up, you just wacked it on and played. you are meant to leave the power on, at which point there should be no noise and then after a minute put standby on, this will go from no sound to sound, no gradual build up in volume.
looks like you broke your amp

While this is true, I don't think it's the problem - the whole standby function is simply to let the valves warm up - nothing to do with the electric flow (or lack of, in the TS' case).

even that wouldn't cause it to do that

Check the transformer leads where it is clipped to the PCB. It's usually the filament lead that will arc and roast the clip, however this lead not fused.

I suppose it's possible this created a surge and took the main fuse with it.

The fix is to cut off the clip and solder the leads directly to the posts and in your case, a new fuse and possibly a set of power tubes.

the studio I got to always have a few 5150 heads in the repair area because people don't know how to let them warm up. if it wasn't for that reason then what would be the point of the whole -power on/standby, thing?

That makes it about 70 or so bugeras that have failed on this forum ALONE.

Why are people still buying them?

The standby function is designed to allow the valves to warm before getting full power, thus making them last longer.

I think you're missing the point - if he had blown his valves, he'd still be getting power and the lights would still be on e.t.c - What this sounds like is a blown fuse, as the electrical current has clearly been cut. The only reason they don't work, is because the amp won't turn on.

yeah thats true, can't argue with that. he should really look after the amp better though

Thanks all for the input, i have taken the amp to a reputable amplifier specialist in my area today, who after having an hour with it tells me the fuse keeps blowing everytime it's turned on, he thinks there is a problem with the transformer/Transistor(can't remember exactly what he said) and has told me to send it back to the store i bought it from, which i am doing £43.00 for postage what a nightmare.
he says the tubes are all fine, but would not delve too deeply into the gubbins for fear of voiding the warranty.
thanks again for the help, i'll let you know how i get on.
