Philco 20 Restoration
#22

Gary, My interstage transformer was still good so I did modification "A".

This is the speaker cone that I used   http://www.electronix.com/speaker-replac...13892.html     Here is a spider that should work    https://www.ebay.com/itm/A-pair-Best-Sub...1438.l2649    I should mention, because of the way the wires inter the speaker, I had to cut out a small section of the spider for clearance.





There is no need for an across the line capacitor. I used .01uf safety capacitors. When there is a .01 cap connecting each side of the line to chassis ground, you have in effect, .005uf across the line.
