So basically my Peavey Valveking 212 has stopped working, can anybody please help me?

The other day, when I flicked the switch to turn it on (Just on to standby) there was a pop, and the standby light flashed on, then stayed off. The amp "died" and there was lights or sound or anything.
The fuse in the back of the amp was broken, so i replaced it a few days later and tried it again, and the same thing happened.

The amp is not particuarly new or old (5/6 months) and has only been used for bedroom practices.

Can anyone point me in the direction of what might be the problem? I am good with guitar electronics, but the inner workings of an amp are a mystery to me.

Any help much appreciated!

Thanks

There are about 401 different things that could cause that. Take it into a tech.

k, then.

here's a schematic of your amp.
power supply is on page 9
http://www.schematicheaven.com/newamps/peavey_valveking_100_212.pdf

not much before the standby switch.
Power transformer,
4 diode
4 capacitors
wiring going to the CT of your Output Transformer.

loud pop might have been one of the diodes.
maybe one of the caps, but usually it stinks like hell when one explodes.

the noise could have been something else, even an output tube socket arcing.

taking this to a tech is not a bad idea, unless you really know what you're doing.
there are high enough voltages in there to kill you.
