I don't remember the resistor number, but it's about 12K (IIRC) on later B's and such; and about 22K (?) on the older models. If I were doing the work, I'd replace it with a 10K resistor in series with a 10K or 25K pot -- the kind with a locking washer -- and then dial it in to my taste. My understanding is that the same resistor may not give quite the same results on two different Hammonds.

Regards,
