You are measuring the DC resistance of the pri wind What is kind of important is the impedance not the resistance. Just hook it up as is. No resistor needed. Definitely replace #46( .006 connected to the plate of the 7B5 or 41) I already forgot which tube it uses. if it is shorted it will take out the op trans. Also the cap in the tone control will do the same.

I was talking about the resistance of the primary and I will not put a resistor in there. But you reference a #46 I don't see it. The tone is #32 and the caps off of 7B5 Output are 30,31 which I have replaced.
