So there are some sounds coming from my amp when I play particular notes on my guitar. Sounds like a guy exhaling harshly thats been smoking for 60 years.

Im thinking some of the notes frequency are reacting with one of my tubes in a jacked up way so this sound occurs. But i'm no amp doctor so any input on the situation is greatly appreciated c:

Thanks, Jon

If you have another set of tubes lying around, try popping those in and see if the sound persists.

also ive noticed when i have pedals plugged in but they aren't on i get feedback. not too big of a deal since i pretty always keep 1 or 2 on but this may make my current problem more apparent to someone experienced with amps.

only on one of the power tubes. i have 6L6s in right now. i found a 5881 laying around. think it would be alright to switch out with the 6L6 giving he noise? just to test it before buying a full set of tubes?

any recommendations on website to get cheap full sets of tubes?

Probably wouldn't hurt to do as a test but you COULD f*ck things up more.

Unless you are desperate, I'd just get a new set.

It is possible I suppose that a microphonic power tube is cause your frequency issue but I'd be more inclined to think it is a preamp tube. Buy a new matched power tube set and 1 JJ 12AX7 for rotating. If you don't notice any differences with the preamp tube swapping put the JJ in the phase inverter spot.

That's probably what I would do, but I'm not at amp tech.

i always thought 5881 and 6l6 tubes were generally the same thing.

but okay thanks man ill take a look at those sites c:

No.

I wasn't saying that because it is a 5881. They are the same tube.

I'm just saying randoming throwing in 1 power tube into a mix 'can' be hazardous to your amps health. For testing purposes - it will probably be fine. Just monitor the power tubes real close.
