Hi Les
Another thing to consider is the voltmeter you’re using to take those voltage measurements. Your radios schematic voltages may have been taken with a 1000 ohms/volt meter back in the day. Since that type of meter put a considerable load on the circuit being measured their readings will be lower than yours especially if you are using a relatively new meter with much higher ohms/volts. A VTVM or a modern digital meter puts virtually no load on the circuit being measured. As a result, your readings will be higher by comparison.

ps: I also use Bucking transformers on all my vintage radios, just to help reduce line voltage stresses.
