NEED HELP WITH CRATE BV300H(alltube)..NO SOUND : (

[pauloZ]

i don't know much about amps. please i would appreciate your cooperation on this one.
yesterday that i tried playing my amp, no sound came out of it at all. All seem like it worked fine when I first when it turned it on, the lights go on inside the head, it warms up, but after i get it out of standby, no sound comes at all while still on. I really dont know if it has other fuses besides the one i checked, which its fine.
i really don't want to take it to the shop, i get ripped off.
i left the amp overnight outside once, it was not raining,so im guessing that could of have done some damage , i dont know.
any guesses on what could be wrong with it ?
thanx

I'd begin by checking simple things like the speaker cord - it could be bad, or plugged into the wrong jack. On some amps, the external speaker jack should not be used for one speaker.

Does the amp make any sound at all?
Hiss? Hum?

As Enzo says, patch a cable from 'preamp out' to 'power amp in' to see if that recovers the signal.
