The PHILCO Phorum

Looking at re-capping a Sparton model 835 chassis and found these odd looking caps under there.
A few have a crusty coating on them as if they were leaking.
A couple shown in the picture don't have the crust, but look like there is a wire winding under the coating.
Are these a different style of cap that Sparton used in 1935, or are they something else?
I am used to having the cap values clearly marked on the paper and wax caps.
Apparently on this radio, you have to chase them down on the schematics.
Anyone have any suggestions here?

? Link isn't working.

I believe they are chokes I had some of them in my sparton 1466.

Ok, but what is the crusty coating on the center one?
Others have tar like covering on them and one has friction tape wrapped around it.
There are several of these critters under this chassis.

Ah yes, photobucket works sometimes and not other times.
I just clicked on the pic and it did work.
Go Figure.

and ... to the opposite end of the rainbow....

the object i am pointing to here *******IS NOT*********** a capacitor..
which kinda blind sided me because this is the first time i ran into these which are resistors.

Yes. Those are wire-wounds. Used quite a bit, in Philcos, in Zenith TOs. Probably in other places too.

Well, I found after tracing them on the schematics, that the crusty looking one is a capacitor and the smooth looking ones are indeed wire wound resistors.
Re-capped it and its now playing pretty good.
Could use more volume, but it is pretty clear.
