You are correct regarding the voltages
The PK3 can handle 90 VAC and 1000 VDC
The 309C can handle 30 VAC and 500 VDC
Heathkit made the pk3 rf probe and the 309c.
I think the pk3 was used for tube testing.?? plus it can handle higher voltages as it has three didoes compared to one on the 309c

Does anyone know of a schematic for building a RF probe for the Heathkit Tubers?? I found one online but can't read the component specs.
This would be used VTVM or a DMM with 10 meg ohm impedance??
