Philco Seventeener II

[Crist Rigott]

While recapping the main board I ran across this:



This is K2 and it has a 500pf cap added to pins 5 & 6. Here is the schematic of K2 and I penciled in the added cap.



Here is the part of the schematic that K2 is used in. It is in the audio section just after the volume pot. Again I penciled in the added cap.



Any idea why this was done?

If you look closely you'll see K2 is missing some coating on the face and on the top in several areas. I'm going to build a new one. Any idea what I should use for caps?

Thanks.
