Surge-supressor resistor in power supply

[frenchy]

Follow-up:
Filament voltage with existing damaged suppressor after fully heated up = 6.44 volts
Voltage with resistor bypassed = 6.7 volts

So not spectacular but nothing to sneeze at either, 1/4 of a volt, that's about a 5% increase in the filaments. I'll see if I can notice any slight improvement in the brightness out of the pic tube with the booster off of it and the resistor bypassed.
