Eric, thanks for the ideas I will use them all.. will check that in the morning. One thing I I wonder if I see no other problem is it possible the resistor just gave up? tube might be good etc....id there a way to check the 811a via resistance checks etc? it looks good ... thanks

Check the hardware for the tube sockets, and make sure there are no nuts 
missing on the underside of the chassis. I repaired a 2K not once, but 
twice, due to hardware vibrating off of the tube socket, causing one of the 
tube filaments to loose connection. It's been a few years, so I don't recall 
which socket it was, but it was enough for one of the tubes to loose 
filament voltage.

Maybe when you changed tubes, the socket hardware shifted ever so slightly, 
enough to re-establish current flow. After the fan/blower ran awhile, maybe 
it moved enough to loose connection once again.
