You are right, this is a significant factor, using the modern DMM, but honestly I haven't seen the voltage in question being what it is in these two cases, when measured with my Fluke.
And I have restored a 620 fairly recently. As well as some similar radios.
One thing is to bring down a plate voltage that is fed via some serious resistor, and another - to lower the voltage fed from the rectifier through maybe 1K resistor (field coil). There will be a difference, but a 100V?

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
