Hi Tim,
Before you get carried away. The tested voltages you show would seem to be correct. Tubes like the 71's normally never were operated above 180 volts and voltage drop through plate reactor seems correct at 135 volts. The second picture you posted shows/ states that tube #7, a 227 has a plate voltage of 160. That's what you found. I think your troubles are elsewhere in the radio. You could have shorts in the trimmer caps, opens in the coils, etc.
Have you tried signal injection starting from the 71 output back to the 1st RF amp.
Ed
