[Boatanchors] Hammarlund Super Pro 150 question

 Greetings,
I'm overhauling a SP150 I got a few years ago. The sensitivity control is
bad. The resistor element is missing pieces. Therefore I can't measure the
end to end resistance of the original for a correct value.

The schematic of the SP150 is apparently identical to the SP110 minus the
crystal filter. But the sensitivity control resistance is not called out in
the service data.

Does anyone know the value for the sensitivity control?

Thanks..
