I've moved on to resistors now and was surprised to find this 70K open. It's part of a voltage divider that feeds all the 24 screen voltages.

Also, a 490K resistor going to the RF tube AVC cap had doubled in value.

I have not fired it back up yet and am curious to see if the is any performance improvment.

Speaking of 24 tubes. I noticed the tube chart and schematic all call for 24s while I'm using 24As. Am I correct that 24As are superior and completely compatible for this radio?

The Philco 90 speaker arrived today. The cone, spider and frame are in good condition, but alas, the field coil is indeed open.

I removed some of protective wrappings in the hope of finding a break but no luck.
I also experience sticker shock when I priced a one pound spool of 36 gauge enameled magnet wire at $50. When did wire become so expensive ?

I'll start slowly unwinding and hope I find the break near the outside. If not, I'll try to get the pole out and rewind it.
