So I have a Philco 80 I picked up and just like every other Philco from this era it has two open coils. The primary for the antenna and the one off the Cathode of the Oscillator 36 tube.

I was curious of anyone knew the number of winds, the direction and gauge enameled magnetic wire to use in re winding these coils?

It looks to me like
-Antenna primary is 17 or 18 turns of 36-38 gauge wire clockwise.

-Osc cathode coil, 17 turns, clockwise of 38 or lighter gauge.

Anyone have any info on this to verify.

Also I noticed on the 80 schematic it has the cap#5 (710uf) and resistor #6 (10k ohm) going from the cathode of 36 to ground in series with the coil.  Mine seems to have #5 and #6 in parallel with that coil...?  It looks as though #5 and #6 are going to the first terminal of the coil.

Also mine is a very late version of the 80 with round coil cans  etc.  was there a circuit change in this area possibly?

Thanks
