Hi Mike
I cleaned the grid caps and the connectors and still have the problem. I Just replaced the 6f6 tubes again no solution.

Almost 30 years repairing radios and this is one of the toughest.

It isn't just a matter of cleaning them, sometimes they need to have the joint re-soldered, the lead due to internal breakage, and the cap itself due to a deteriorating solder joint.
