Title: Question on bias potienometer on princeton reverb...
Post by: Stuff4bikes on November 28, 2021, 03:32:28 pm

I don't have a trimmer/pot like the type pictured.....will using a standard cts or alpha pot with the three lugs on one side work?

Is the bottom lug on the trimmer/pot the wiper?

The bottom lug on Hoffman’s diagram is the wiper as Sluckey posted but on the pot you intent to use the wiper is the middle lug.
Correct me if I’m wrong.
