Noise in right channel

[mrravioli]

Hi guys,

My crack (with speedball) makes some slight noise in the right channel after 30 minutes of playing. The noise goes away if I turn it off for a couple minutes and restart it or slightly adjust the plug of the tube. But the noise comes back after several minutes.

I'm not sure whether it's the tubes or the crack that makes the noise. Looking for advice.

Thx

If moving the tube makes the noise go away, you might just have dirty pins. Try cleaning them with some Scotchbrite or fine steel wool, then insert and remove the tube a few times to clean up the socket a bit.
 If you still have noise, take a close look at the solder connections at the tube socket...John

It works. Thx a lot!
