      Don,

       

      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??
      Thanks
      Dan
