Oops, Ron and I overlapped postings. Gotta run.
------------
Figuring out how to replace the electrolytics in a power supply usually takes some creativity to avoid flying leads. Since you can't simply parallel new caps on the old cans, terminal strips may need to mounted nearby to get the wires off the old capacitor cans.
Assume this is Rider Philco 4-32. The negative side of the caps connect to the center tap of the high voltage winding. Normally the cap cans had an insulating washer between the can and chassis to make this connection possible and included a solder lug which may be reused to make a negative connection for the caps.
Power up the radio and perform basic voltage checks. Otherwise you are working blind.
As fas the dial lamp not working typically the lamp receptacle has to taken apart and rebuilt with insulating phenolic washer. The rubber washer have petrified not allowing the spring to put pressure against the lamp. Think Ron or Chuck has a help page concerning this known issue.
Good luck on the restoration!
