[Amps] NCL-2000 question

[Mark]

Hello,

Im troubleshooting my NCL and have a question. I have
full plate voltage and Im able to properly bias my
pair of tubes, and I also have proper grid current.
But, I dont have any screen current. I can get full
power output from the amp no problem. I have rebuilt
my screen supply(new diodes)also. Is my screen supply
gone from the xfmr or is there another issue in the
metering circuit? Any comments would be appreciated.

Thanks a lot...
