I have noticed that in several of my Philco radios, that some of the wax paper capacitors are marked with the number "7" inside a circle.

Not every paper cap in a radio is marked this way.

Any idea what this means?   I didn't see any mention to this in the service documents.
Regards,   PeterN

It might have been an internal tracking of some sort. Perhaps a bulk lot number. Take care and BE HEALTHY! Gary

A cap's a cap.

All are replaced by film caps of the appropriate Volts and Farads value.
