I need a replacement speaker for one of these beasts.

it seems this one the critters devoured the entire cone. it is gone.

Thanks.

That a tube type? I've got a couple of slide rule dial tube type TO chassis I could likely get a speaker from.

Yup it is a tube type. Chassis 5H40

I'll see what I have, and get back to you.

Okay this is what I've got. 10$+shipping cost gets you the the speaker, it's frame, the output transformer, and the black frame over the front of the speaker.

I hooked a signal generator to the voice coil terminals and could hear the 400Hz tone through it so it does work.
Send me a PM if interested.
