We're closing out 2023 with special guest Bill Krinard of Two Rock!  https://www.two-rock.com I won't even attempt to annotate this episode but Bill joins us at 5:36 and fields a bunch of listener-submitted questions on transformers with dissimilar primary windings; Two-Rock's design process; how he uses oscilloscopes; Ampegs; Filmosound mods; potentiometers; harmonic content; and more.  Want to be a part of our show?
