My Mother the Philco? Man, now that was a show! Remember the episode where her flyback shorted out! Hilarious!

Well, Chad, looks like you hit the nail right on the head. Pin 9 of the 6LF8 is the plate. I started checking peaking coils in that circuit, the second one I looked for was L101, hmmm, where is it, oh, hard wired under the chassis-EUREKA! Right next to that resistor I pulled out of circuit to check, back when I was hunting down the height problem. And you know the rest...I hit the coil with the soldering gun (or something) & it didn't look so bad but it was enough. Rats.

So, looks like its time for my long overdue lesson in peaking coils. I pulled out the 3-wheeled 2-sided resistor/capacitor/inductor decipherer & set it up for 390uh (what sams says) and it says orange-white-black. The 2 dots I can see on the damaged part are blue & white. Okay. So, where do I buy a new one? I could just go hunting through scrap modules up in the attic but not so sure with this color code question. I have an Allied catalog where I found under "molded inductors" a 390uh ferrite core rated at 105 mA. Would that work? I bet the ratshack doesn't carry them! I'm sure Moyers does but this makes for a pretty small order.
