Philips bypass capacitors in 203U - Specifications? (Techniek Radio/TV)

Hello, I am wanting to write an article about the Philips 203U series of AC/DC radios introduced in 1941. (I have a 204U made for export to Sweden) I see that these radios were "tropicalized" to better survive hot and humid parts of the world. The bypass and larger coupling capacitors appear to molded in some sort of plastic or tar substance. Is there any technical description or advertising about these capacitors available from that period of time?

I understand that some Eastern Block versions of the Philetta were still being manufactured into the middle 1950s. Did they continue to make the bypass and coupling capacitors in the same way?

I have read 45 Years With Philips and am fascinated with the way that Philips was operated under occupation.

Thanks,
Robert
