Re: Vacuum Tube 6EJ7 Test

by lisdon@[EMAIL PROTECTED] Jul 1, 2008 at 02:24 AM

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
