Yodle.

After having my amp on for about 20 minutes, a constant beeeeeeeeeeeeep occurs, the sound is still the same, but with this beep in the background.

I'm just wondering what the problem can be.

By the way, it's not the valves (changed them a month ago and it still does it)

Is it a digital beep? like midi or something?

It's a constant beep (doesn't stop and start again like "beep beep"), nothing from anything digital.

Could just be a dodgy contact or something, have a looksee inside... also shake it and see if anything is loose (not the most proffesional way of doing things but...).

^And yes it might be a radio signal is your shielding is poo.

It's still not my valves....

And I don't think it's a radio signal.
And I'm not an expert about the innards of amps, so I probably wouldn't tell if something's loose, I'll try though.

If it rattles, get a guitar techspert to have a lookie. Unless you have spring reverb, it migh be that rattlin'.

what kind of amp is it?

and it may be pedals too. or cords can pick up interference if the shielding goes bust.

Wait it could be your valves actully. I know you have Sovtek's in the preamp and ive heard they easly get microphonic.

Hmm, I might order some new pre-amp valves. I've got the old ones (same type), I could try and find the microphonic valve by process of elimination? (although the sound still happened with old valves)

And I'm gonna try and take a pedal out of the chain at a time, see what happens.

I've got a Fender Blues Jr by the way.

Hmm... Do you wear a watch on your picking hand? This happened to me yesterday, when ever I would rest my hands on my strings, i would get a little "beep beep beep beep" through my humbuckers, and it turned out that it was my watch!

I had the same problem in my 800 at one point. I swapped around the 12AX7's and problem solved.

Order some low microphonic preamp tubes if that doesn't work.

tubes, bad cable picking up house noise, power supply to a pedal.

turned out to be a bad pedal output.

If not the valves, it might just be the electricity passing through the amp, making the beep noise (Like the buzzing you sometime here, but beeping instead).

Epiphone les paul standard plus (cherry burst)
Flanger Pearl peddle
Marshall G15R CD
Dunlop 535Q wah

I like Epi LP's. You got a problem, PM me!
#17
it could be something electrical because sometimes if I leave my phone by my amp it sometimes beeps sounds kinda like "dun dah dah dun" like you hear on radios
#18
Tried finding the route of the problem, none of my pedals I don't think, might be the power supply as when I moved the daisy chain the noise went higher pitched??? Strange.
And then the problem went when I unplugged the power supply and plugged it in agian.

No, I meant it as in the fact I can stop it by doing that, but I don't want the problem to be there in the first place, so I still need to fix it.

if it happened went away when you unplugged your power supply then your power supply ismaking the noise, thats not an uncommon problem. but if its the tubes the best way to check is to tap the pre amp tubes with a pencil eraser, you should be ableto hear the tapping, since all pre-amp tubes are microphonic to a degreew, but if it makes a bell like chime when you hit it, then its gone bad. do that while the amp is on BTW.

Cheers, I'll try the tapping thing.

And it's most likely my power supply, it's just 2 adaptors (one daisy chained).
I'll try more out tomorrow.
