OK, re-installed the field coil (used an old socket from a wrench set to hammer on to push in the force fit pin--needed to clear the spider screw holder) and re-installed the cone (broke the spider--aaarrrggghhh! But repaired it, mostly) Added new leads to replace the old rotten wire and resoldered them all. Hooked the field coil to 40V DC, and fed the Voice coil from my stereo with some good Fathead blues and it sings again! Whew! Now to attach the 4 pin cord that connects to the Model 90 radio and back to troubleshooting the 1931 Cathedral radio. Thanks to all for the help!
