pic of the coil being used number name on it is as follows:
control corp
7c210

the item read 465K ohms
once removed the voltage at pin 8 6X5 went to 422vdc
I have checked and replaced both c18 B & C
All tubes check good none are weak

I will post schematics show show notes how in certain ver have this coil dis-attached from the speaker.

Its location was next to the power transformer on the bottom.
