Ok remove the 80 tube. Set meter to >500ac. Measure voltage from the ungrounded side of R-12 (should be a big resistor, wire comes from the power transformer) to pin 2 of the 80 socket and then pin 3 of the 80 socket. Should see about 300-350vac on pin 2 and then pin 3 should be the same. If that is OK check R-12 it may be open.
