The filter choke, one of the 2 smaller transformers, is #51 on the schematic only has two connection points. Point (A) let’s say is connected to the big pin (filament) of the #80 tube the other connection coming out of the filter choke is point (B) and connects to #53 the 8 ufd cap.

With the set turned on and using DC voltage measurment (not sure if that is the right setting but figured I'd use it since I was using it for measuring from the #80 pin), I measured from the filament of #80 to point (A) on the filter choke just to make sure that I was using the multimeter properly and got 0.0 V which is what I was expecting since it’s essentially measuring from one end of a wire to the other end so there should be little or no load. Then I measured from that same point on the #80 (the filament of #80) to the far end of the filter choke, point (B). I expected to see a jump in voltage but it was fluctuating between 2 and 3 Volts.

So, 2 and 3 Volts is pretty close to zero. Doesn’t that mean that the choke is "open" because there was no load, no electrical potential difference? Shouldn’t there have been a noticeable voltage change? Or do I need to unhook the #51 filter choke and measure it separately because the other caps are also being measured here since they are part of the circuit?
