I just got done checking the CRT's, both are bad, not unexpected for a Predicta.
These must have been replaced at some point because neither one had a 2.34v heater, they were the normal 6.3.
The one in the pedestal had no cutoff and almost no emissions so I blasted it with my B&K, it now has really good emissions with the cutoff control in the middle but the cutoff can't be set the usual one division above zero no matter where the control is set, I suspect it'll work but with unknown quality.
The Holiday also checks nearly dead, the cutoff works and if I crank the heater up to 8 or 9 volts the emissions are in the green so it could probably be run on a brightener for a while.
So the search is on for at least one good tube, I'll still clean them up and probably recap the Pedestal in the meanwhile.
