I've got a Philco 90 chassis with a single 47 tube. There is a bakelite cap connected to part 55, which is the choke. The part is a 4989-J, which is a .09 cap. Both wires of the choke go to this bakelite cap, and one line goes to one electrolytic and the other goes to the second electrolytic.
I replaced the electrolytics and powered it up, and it plays just fine.

It's clear that this is a Philco part, and it looks like it is original to the chassis. Has anyone seen this before? I don't see it on the schematic nor on the under chassis layout.

Thanks,
Chris
