Update on Model 87 restoration
#2

Great! Sounds like you're off to a good start. While you wait if you've got three .1mfd 350v or better I'd repair the plate bypass caps for the 26's. Just break the ground connection where the wire is solder to the mounting bracket and solder in the new one from the solder lug to the bracket(ground connect).

Also take flashlight and look down into the rf coils. What you are looking for is loose wire coming from the coil. If you happen to see some you will have to rewind that open section. Usually it's the primary winding which is about 30 turns of small gauge magnet wire like 32-38G enamel covered. Number of turns isn't real critical as it is for coupling not the tuned circuit.

I'm listening to mine as I type. Tuned up on WNAR Crime Club is on now but later one of my favorites, Jack Benny and Amos & Andy will be on.

Have Fun!!!

figure out what all those squiggly meant.

Now I think I've got!
