Philco Model 81B

Measured the plate pins again and the resistance went down to 100 ohms across and 135 and 160 to the center. I went ahead and powered it up on the variac and about 35 volts the tuning lamp came on. Took it up gradually to 110 volts. The filiment voltage for the tubes got up to 2.9 volts. Then it smelled like something burning and the pt got pretty hot and was humming. Shut it down. I believe that the pt is bad.
