PHILCO 41-290 ART DECO CLASSIC
#9

OK, I am ready to start on the electronic restoration of my 41-290. I pulled down the "Replacing Capaciators in Old Radios" article off the Philco web site. Here is what I came up with taking readings off the caps themselves:
Non Electrolytic paper caps:11
2X .o5 mfd/200 Volts
1x ? mfd/400 Volts (part # 30-4518s)
4x .01 mfd/400 V (part # 30-4572)
2x.003 mfd/?V (part 4469)
1x .002 mfd/?V
1x ? mfd/? V (part 4472)

Two Electrolytic Caps
1x 12 mfd/400v (axal lead)
1x ? mfd/400 v (dual lead on one end)
The schematic I pulled down off the web at Nostalgia Air is in a very small font and I have trouble reading it. Also, it doesn't have the same complete parts list like I have seen on the some of the Zenith Schematics that inlude mfd and Volt rating in the parts table.
So, can I use the standard orange drop capacitors to replace the paper non elctrolytic using .05 .01, .033 and .022 replacements? Can somebody help me with the unknown Voltages and Mfd rates shown above?
As to the electrolytics, have I identified them all? Of the two I have id'd, can I use a 22mfd/450 or 630Volt replacement for the 12 mfdx400 V? What about the second one? Both of these were found underneath the chasis held in place with a soft metal clip to the chasis. Also, I can't seem to find a dual lead Electrolytic cap in my RD catalogue. Any tips?
Any assistance would be greatly appreciated.

Thanks much, MG
