Atwater Kent paper cap markings
#5

My experience on A-K house marked caps is that the same "code" is consistent with that radio model. Chances are that same code is used in similar models. too. However, I have found that is not true of A-K resistor color codes, for example, a white (all white dog bone resistor) FWIR, can appear in two places in the same radio at different values.

That said, when restoring, care has to be taken not to be deceived in both capacitor codes as well as resistor color coding schemes on sets built before RMA became standard practice.

I cannot vouch to where I read this, long before the WEB that Philco used RMA codes but values chosen of such the colors would stand out in the factory lighting scheme.
