I would look at the preamp to troubleshoot first.

Try changing V1 or V2 and see if the problem persists.

I don't know anything about your problem, but why do you leave it in standby for 15-30 minutes after playing? The standby sequence is only needed when starting the amplifier. Using standby, especially for that long after use, just wears down the tubes.

Sounds like a preamp problem!

Use standby if you are not going to play for more than 30 minutes.

Doing so saves the life of the tubes.

This got me thinking ...
