In a radio without a power transformer, your resistance across the line cord plug should be 150 to 250 ohms with the switch turned on and the set not plugged in. This is the filament load. If it is infinite, or a large number like 100,000 to 200,000 ohms you have a burned out tube or faulty connection at a tube socket, bad line cord, or bad/gummed up on/off switch. Measure this before you plug the set in. Of course, you will not generate any B+ if the tubes do not heat up.

I tried to post a similar message a few minutes ago, so if this is a repeat, forgive me.
