Hallicrafters T-506 Late Production Set

[M3-SRT8]

The bottom of my HV Coil assembly has a resistor on Pins 5 and 6. It doesn't show up on the schematics that I'm looking at (late production 6AU6 T-54) and I can barely read the bands. I THINK it's Green-Black-Yellow. 500 kohms. Half watt.

It tests OL on my Fluke. The 6C4 oscillator is such a critical tube so I want to get it right. My HV Coil board has two .25uF 600V and one .001 6kV.

Any ideas, Gents?
