aren't your driver tubes in pcb mounted sockets?
I once gave myself some sweet 120HZ hum in a little used guitar amp changing an input tube on a pcb mounted socket ... don't know if it was me or the prior owner but someone lifted & broke a trace!
went nuts figuring it out ... well, actually I didn't, my cousin did, I still went nuts though!
it sure sounds like you've got a similar grounding issue with a socket
just a WAG because you said it improved plugging and unplugging tubes
do you have any freeze spray you could spray around the sockets & see if there's changes? might be worth a shot
with regards,
