Marty, it might be time to do a little diagnostics now. Hoping you cleaned tube pins and sockets. I would hook my volt meter to the plate of the output tube and see what you can see about the B+ when the radio dies. This should tell you if your problem is in the main rail something like the field coil or the output xformer primary.
