I am restoring a Philco 37-624. This is a 6 volt DC set.

http://www.nostalgiaair.org/PagesByModel...013214.pdf

The filter capacitor, #34 is non-polarized, 2+8uf at 200 volts. Is this because the B+ will be negative if the 6 volt source is connected backward? It uses a synchronous vibrator.

If I wish to restuff this can capacitor, what would I use? I have seen 2.2uf film caps, but they are large. I have never seen an 8uf film capacitor. I suppose I could just use normal electrolytics, such as a 4 and a 10uf at 250 volts and just make sure to connect the radio to 6 volts correctly. Any other recommendations?

I have restored many 6 volt sets, but this is the first one I have seen that used non-polarized filters.

Dan Double conversion is using two IF converters instead of one. This improves the image response. morzh — 07:15 PM
