Hi all,

When I was restoring my Philco 90 (single 47 output tube) chassis, I found three paper capacitors which are not shown on the schematic or in the Philco drawings. See the circled caps in the photo below.

[Image: http://i135.photobucket.com/albums/q136/...hLight.jpg]

Two of them are Philco brand and the third is some off brand. All are .05uf. From what I can tell, they seem to be in parallel with caps that are in the bakelite blocks, drawings #18, 26, and 46. Do you think they were added by a repairman? Or is it possible that they were part of a product design change?

Oh, the paper block capacitor on the chassis right side wall is definitely an added unit. It was installed 10-10-36. I have removed that unit since this photo was taken.

Regards,

Ed
