Having Trouble with my Tube Amp...

I have a Peavey Valveking 100w head, and I've been using it and everything has been fine, then I tried to turn it on today and the red light came on in the front when I flipped the power switch, but the tubes are not lighting up. I took the amp off of standby and no sound. I don't think it would be the tubes because I thought that they glowed bright red or blue if they were no good, and I'm just getting no lights whatever. Perhaps a VERY VERY dim light, dim enough to where it's barely noticeable.

I'm thinking it's not receiving all the power or something like that. Does anybody have an idea what might be wrong with it? or how to check to see what is wrong with it? Because I called a local authorized Peavey dealer and they want 52 bucks just to look at the damn thing.

Any help would be greatly appreciated.
 
Pull the fuses and make sure none are blown. Same thing happened to my Randall tube amp once and all it was, was a fuse.
 
ok i'm not too start with this stuff, what does the fuse look like so i know what to pull out? and how do i know if it's blown?
 
i unscrewed the fuse from the back of the amp, then tried to turn it on and the red light did not come on, what should i do now? is it possible there are other fuses that could have blown?


the fuse is not clear though, its not dark, its just completely white and i cant see through, could this also mean it has blown or is it simply not a clear fuse?

the amp wont turn on without the fuse in there you fucking asshole.
 
problem is, i can't afford to bring it to an amp specialist, im gonna have to do some shopping around for a good price, but thanks


ps, tom and i are friends, so he is just busting my balls
 
what kind of safety pre-cautions could i take so i could maybe do this on my own? perhaps heavy duty rubber gloves?

Um, no. If you don't have at least a good basic understanding of vacuum tube electronics, you should not attempt this on your own. Sorry, but you wouldn't try to take your appendix out yourself if you didn't want to pay a doctor, would you? In either case, you could die, and that's no exaggeration.

BTW, if it is one of those internal fuses, it's not very likely that the blown fuse is your only problem; something took out that fuse. Even if you did get the blown fuse replaced, it would probably just blow again. All the more reason to take it in.

oibviously you dont have the required skill set to work on this yourself... and when it's broke aint really a good time to start learning it...


as to looking for a deal on a tech... this comes under the heading of false economy... how much have you saved if the guy takes 2-3X's as long to fix it??? find a good tech and pay him what he's worth... if we keep this shit up no ones gonna want to be a tech and then where will ya be ??? buy ing a new amp because ya couldn't get anyone to fix it....
 
turns out the tubes got loose in transport, so i pushed em all back in and everything is back to normal

Well, who transported it? FedEx? Or UPS?

I would think that's some pretty rough transport to make the tubes come loose out of their sockets. WOW! Either that or Peavey put some pretty darn scummy tube sockets in there....
 
no i have had it for a while now, i meant while i was transporting it from my practice place back to my room


i try to be very careful, ill just be a little more careful from now on

switch it on stand-by when you're done, let it power done for five minutes. Hot tubes are delicate!
 
yeah im really good about let it warm up for at least 5 minutes, and then i keep on standby for a while, and if i am transporting i usually let it sit for a few minutes before i unplug it etc


but thanks everyone for the help

You're quite right :o....well, put it on stand-by, switch it off, and dont move it right away.

I never use the standby switch unless I'm letting the amp sit for a while powered up and I don't want it to make any noise, otherwise I just flip them both on and off together. I've been playing through tube amps for 40 years and never had any other need for standby. Some of my amps don't even have a standby switch.
