I had a little more time to look at the circuit today and make some
measurements. I reset the plate and screen grid to 200 vdc. I varied the
g1 voltage from -5 to -2.4 and recorded Ib at normal levels. Ic2 also
seemed normal. I have g1 connected to cathode through the 10k resistor.
I
need to look at a few more things as I am told that these tubes were not
outputting up to spec. I can't recreate the circuit they were used in so
I'm just doing the best I can to verify they have low output. So far they
seem ok. Any thoughts?
Thanks,
Don
