Philco 20 dial lamp
#8

Yes, you're right, it's the amplifier filter choke.  Sorry for the confusion.  
I think that its physical decomposition may have been exacerbated when I blew some dirt out of the chassis.
I also have a dim recollection of having noticed it when I fired it up (and did a less thorough cleaning of it) in my younger days
back when I first acquired it.

I'm looking for a replacement.  If anybody knows of one or has one, that'd be the next thing on the agenda to fix.

Also, (I hate to ask, I know that everyone here knows a LOT more about this radio than I do) if someone could please post a photo of the lamp connection points to the tube sockets, I'd really appreciate it.  I've read that it taps the filament pins on tube #27 and I I have the leads run right to it-I just don't want to make a "dumb"
mistake. I believe I have some #43 lamps on hand.  Will that bulb work?  Or do I have to have #40's?  I've also read that #13 bulbs will work as well.

 I've worked on a few tubed amplifiers over the years, mostly just retubing hi-fi and a couple of guitar amps and then adjusting their bias.  My discomfort level with this older gear is higher and this one's a "keepsake".  Thanks to everyone who's taken the time to help.
