[Boatanchors] Hammarlund Super Pro 150 question

[Joe Connor]

 Wally, you might want to contact Mark Oppat. He's good people and the go-to guy for volume controls etc. Maybe he can answer your question and supply a suitable replacement.

     I don't think the overall design of the Super-Pro changed a 
lot so compare the SP-200 and see if the values of other 
resistors nearby are similar. If so go with the value of the pot 
in the later version.
