If you turn on the power switch and measure between the pins of the power plug you should get around 6.4 ohms. You should get an open circuit between either pin of the power plug and the chassis.

Between pin 4 of the 5Z4 socket and the chassis you should get about 200 ohms. Between pin 6 of the 5Z4 socket and chassis you should also get about 200 ohms. This seems to jive with what you mention in your last post.

Between pins 2 and 8 of the 5Z4 socket you should get 0.2 ohms. You should get an open circuit between either pin and the chassis.

Between pins 2 and 7 of the 6F6 you should get 0.2 ohms. Between one of these pins and the chassis you should have a dead short. Be sure to remove the dial light before taking measurements for this winding.

If you disconnect the center tap of the B+ secondary (winding connecting to pins 4 and 6 of the 5Z4) that should isolate all the windings from one another and you should not get any continuity between any of the windings.

On your PMV you do have the light bulb wired in series with the radio and not in parallel, right?
