37-620 voltages
#2

The voltage on the 6K7 plate is rather high so changing 29 to 82K might be a good idea. The other B+ voltages seem to be OK. Measurement devices in 1937 had a wide range versus today's high impedance devices and today's higher line voltages throw them off even more. My philosophy is the pwr transformer is 70-80 years old and you will want to be as gentle as possible with voltages. So I put a dropping resistor in the primary to bring the voltage down to about 115.
