Ok so your output transformer is ok and the wire with clip lead goes to the + side of the 40uf cap. I'm a little concerned about the field coil resistance as it's used the set the negative bias voltage in the set. With it being lower in resistance it will lower the bias voltage. I suppose if who ever change out the spkr may have add a series resistor between that loose wire and the - side of the 15uf cap @600 ohms at 15 or 20 watts. If not I would check the negative voltage on pin 4 of the 42 tubes should see about -15vdc.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
