Need help crosley 124 capacitor block.
#1

Between bad quality schematics and no part numbers i need help figuring out what kind of values of capacitors are in this can.
It has five leads one being a ground the other bath tub caps are long gone except the one mounted on top of the chassis.
Here is some pics i have highlighted the trouble area.

Perhaps this will help. https://www.americanradiohistory.com/Arc...32-ABC.pdf  Go to the Crosley section and it's on pg 11.

What's in this box?? Depends on where the wires go.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!

I think that's a capacitor block, but like Terry said, you just have to trace out the wires:

Redrawn schematic that might help:

And here is a restoration thread that might help (note this chassis was used in both the Grandfather clock radio and a cathedral radio):

Crosley was notoriously cheap and did not install a part where it was not needed.
Also, most of the leaky cap values can be found with a 60hz bridge an old school test set that many cast aside for blinking LCD screen digital what-zit do-all lie meter. All but the high end DVM's can deal with a leaking cap and give a value...

Once learned reliance on guesswork and Elmer goes away....

BTW, most of the contents of "box" caps can be installed in the chassis as they are much smaller and can be mounted directly at the point of use. Fact is the chassis is so low gain that long leads to a remote location for bypassing is tolerable.
