Philco 38-10 Restoration

[omegaman]

Got this nice Philco 38-10 radio. In very nice physical condition.

What are the wire connections on the back for RED, BLK, GND?
Does that 5Y4G rectifier tube look okay?

The radio shows evidence of previous service in 1947. The filter caps look replaced. There are some mods under the chassis and one control seems to be a replacement

I will clean the complete unit of dust and grime
De-Oxit the controls
QD Electronic non-residual cleaner for the tuner vanes
3 prong power cord tied to chassis ground

All major capacitors replaced
New lamp GE-51
Check all resistors for out of tolerance

Any special advice for this radio, like the rubber mounts or anything else that would be helpful
