Hi Charlie,

I'd run the filaments only for a few hours and then use the variac to
put the h.v. at 1 KV and put the amp in transmit and let the idle
current run for 10 minutes or so.    If no problems I'd put in on full
B+ and try it with drive.

I don't know how those tubes are gettered--I don't know if the anode
has to show color or not.  I have cetrons in my 75 m. rig modulator
and they're good 572Bs.
