What did pin 4 measure? If you have dc voltage on pin 4(screen) and nothing on 3(plate)I'd suspect the primary of your output transformer could be shorting to ground. You could also try measuring those two pins in respect to chassis ground. Any voltage readings on those two pins will indicate if there's a short in that transformer primary.
