Golden Tube SE 40 Hiss and Pop problem - Thoughts?

My golden tube se40 is hissing and popping from one channel, and it's getting worse. Anything come to mind?

I know this is a badly designed amp, but I like the sound, just hate the reliability.

For some reason, I'm thinking this was indicative of caps or resistors, forget which. If it was just a tube, I'd be very happy, and need to dianose that.

Thanks,

Check tube sockets! The GTA SE-40 did not have the best tube sockets. With the amp cold, take out the tubes for the channel making the noise one by one and reinsert, as to not change the placement or order of the tubes.

Frequently it's the 6SN7GT input tubes that are the culprits. Sometimes tubes will "walk" slightly within the sockets as they heat up and expand, then cool and contract.
