Hello PHORUM members,

I am still working on restoration of my PHILCO 37-640.  I want to start with rewiring the IF cans   What gauge of wire should I be using?
Also can anyone tell me where to order the rubber grommets/shock mounts that mount on the tunning capacitor?  Thanks--John

Are you talking about rewinding or rewiring?
For rewiring, meaning runnin wires to the coil from other components, the AWG does not matter much.
Any wire of a reasonable size that can be worked with, from AWG18 down to AWG 26 with proper voltage rating will do.

Grommets are at Renovatedradios.com

Or at Lowes/Home Depot.

Thanks for the info but I doubt that a hardware store would be carrying the proper tuner assembly support mountings for Philco tuners. Also, you mention wire guages of approriate voltage--What is the voltge?

[morzh]

Renovated Radios do carry what you need.

As for the voltage, a wire should be at least 300V-rated.

A pair of wire strippers can give you an idea of what the existing gauge of the wire leads are in the IF can, I think it's likely 20 to 22 gauge, though may be thicker like 18. I don't have a 1937 model Philco on hand so I couldn't' tell you what they used, though I believe it was cloth covered, so it usually holds up unless it was disturbed or chewed on by a rodent.

Thanks to both members for your help regarding wire and tuner mtg supports. regards--John

If the wire inside cans is the gauges you mentioned, the sole reason for that would be mechanical, to stiffen things perhaps.
Electrically, even AWG26 would be just fine. Any thinner, I would have to see if skin-effect would be an issue (doubt it).
