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.
