No Ken , the tubes are used in a RF circuit . I can't take a amp reading off the
circuit without loading the circuit with RF . That is the problem .
The voltage is too high and is driving the tubes too hard and turning the plates
RED in a matter of seconds . The tubes cost $ 93.00 each and I don't want to
kill them . There is no RF on the filaments but only on the plate caps . Thanks

Thanks James , I can't read the amp load because this is a Radio Frequency
circuit. Any suggestions ? Thanks ,

RF on the filaments?
