More details:
Dual MV pot reads ca. 250k. Wired as (dual) "variable R".
NFB-R is 47k @ 16 Ohms.
Volts reading in the table during vid for the „high“ setting.
In the "low" setting, voltages in the preamp too drop by roughly 10%. B+ drops from 460V to 420V. Also the bias changes (that's why there are two bias pots) depending on running it in high or low Volts mode.
