[Boatanchors] Hickok Tube Tester 539C SHUNT pot

["Yongsurk Lee, HL1FB"]

Hi

      I am repairing a Hickok 539C and found the SHUNT pot  is bad.

It is a 1000 ohm single pot. Does someone have one for sale?

Its Hickok part number is 16925-88.

Or I can just use a commercially available 1k ohm pot?

Is this a linear varying type or non-linear one?

Thanks in advance from Korea.
