You may want to read this page on my site:
http://www.philcoradio.com/tech/60evol.htm

The negative leads of both electrolytics (45) and (46) connect to B-, NOT ground. Electrically, this is the junction of the center tap of the high voltage winding of the power transformer and the top of "B-C" resistor (47) as shown on any Model 60 schematic.

The positive lead of electrolytic (45) connects, electrically, to the junction of the screen grid of the Type 42 tube, the WHITE lead of the speaker wiring harness (which connects to one side of the audio output transformer as well as one side of the field coil). This junction is also part of the main B+ feed for the entire set.

The positive lead of electrolytic (46) connects to the junction of one side of the 80 rectifier filament and the GREEN & WHITE lead of the speaker wiring harness, which connects to the other side of the speaker field coil.

Check wiring to the dial lamp holder.
