ANY IDEAS GUYS? Thanks again for the help.

Banging on the case helps? Maybe you've got a cold solder joint.
Know how to solder?
Also? Tube Sockets can work loose over the years. I understand their is a way to retension them, but I don't know how.....

MIGHT be time for a tech....IF you can find one familiar with tube gear.
