When I started testing this CRT was totally dead - zero Cutoff and zero Emissions.
I used the Auto Restore feature of the CR70 and brought "Lazarus" back to life.
Got good Cutoff setting and Emission deep into the Green.
Then I got a G1 Short.
So, I use the Remove G1 Short feature and got that fixed.
BTW, I had to run the Remove G1 Short feature about 5 times before I
got it cleared.
Filament current is still 90ma at 6.3v.
Right now my 21FDP4 is looking very good. I'm gonna let it bake for
a while to see it this holds.
