Assuming you have B+, and all the tubes light, most of us start by testing the audio section (you should get a little hum when the volume control is turned up and you place ascrewdriver on the middle leg of the volume control. If the audio is ok, work backwards with a signal generator to isolate the problem area.
In a set this old, for performance and safety you should replace all the wax bypass and coupling capacitors, not just the electrolytics. Do 'em one at a time.
Don't know about the toggle switch. Does it look like it was always there, or was it a modication by a previous owner?
