Amp Trouble (I think?)

Well, I play through a Peavey Deuce, but lately I've noticed a high-pitched ringing when it's turned on. I can't really be sure if this has always been there or not, but it sure would be nice to get rid of it.

Has anybody else experienced anything like this?

I've also heard that this is just a result of the tubes heating up. Is there any truth in this claim?

I've never heard it in my amp.

Edit: sorry that didn't really offer much help did it:P

Sounds like feedback turn it down a little

Definately not feedback. It occurs at all volume levels, and doesn't interupt my guitar at all. If it were feedback, it would take a moment to kick in, but this is a constant ringing noise.

Can you record a sample for us?

Have you sited it close to any other electrical appliance?

Not an expert at this, but sometimes this happens to me or something similir when i am using a guitar lead of little quality or a lead which is on the verge of needing a new one maybe.

A@ NCFC91:-

Yep. Quite right. Also check connectors and connections.

Yeah, could be. My cables aren't exactly high quality, and I'm running them through about 4 stomp boxes.

Also, the amp is in a room with 2 computers at either end. I'll take it out and see if it changes anything.

Thanks for the suggestions guys.

The stomp boxes may also be the problem, I know nothing about them myself but I do recall reading something about them having to be wired in in a specific order. Just a thought.

Hmm, I don't think wiring them in a different order will do any good. The signal still has to pass through each one.

good be a soldering problem. too much signal shooting through your amp. check your electrics in your amp. crappy cable can be another problem. check out borrowing a noise reduction pedal...may solve the issue.

Might be an interference with the PC's.

is the ringing comming through the speakers or is it comming from the chasis ?
if it's from the chasis then it could be time for a retubing. i did
have a 5w peavey valve king and the output tube used to ring when played.
it could only be heard at low volumes. daddy's claimed it was normal
when i brought it back to them. i've had several tube amps and none
had ringing tubes.


EDIT - something i pulled of another site in relation to preamp tubes

Q: I have a microphonic preamp tube, do I need to replace it?

A: Possibly. If the noisy tube is in a gain stage or reverb position, then yes, it should be replaced. However, before you spend money on a new tube, you may have another option. Does you amp have tremolo or vibrato? If so, it most likely has a 12AX7 tube that is used as an oscillator for the tremolo/vibrato circuit. This is the least critical tube position in your amp and one where a microphonic tube will have no effect on the tone.

So, assuming both tubes are the same type (usually 12AX7’s), try swapping the noisy preamp tube with the tube in the tremolo/vibrato position. You may resolve your noisy tube problem and it didn’t cost you anything!

I know what you're talking about, but it's not that kind of ring.

I'll give your other advice a look when I check out my amp, eventually. :P I don't play electric very often anymore. Heheh.
