Good news CRT seems to be good.
I know why the CRT had a brightener. There's a short.... I'm not sure where since it didn't register on HK or G1 shorts scale on my tester, but without the brightener the meter pegged on cutoff and emissions (WHICH ISN'T RIGHT), but tested with normal cutoff behavior and good emissions with the brightener in series....With the brightener in series I got my DMM on the heater pins of the base and dialed around my meter till I got 6.3V and that's where I took my emissions reading. This should be repairable without CRT swaps.
