Hey people question about biasing KT66 tubes in my HRD 4x10.
I got a new set of Genelax Gold Lion Kt66 tubes to replace the 6L6s(was advised this would be okay by the place I bought them) the problem is with my bias adjustment pot all the way down, I'm getting a reading of 104mv at my bias test point. with a plate voltage of 470v-480v on the hotrod and the tube rating at 25w, I'm positive that these are running too hot and i cannot adjust it any lower. BUT I played through it regardless for about 30 seconds and I loved the tone of the tubes. Is there a way to Mod the bias circuit in order to accommodate the new tubes, or maybe I'm missing something. Thanks all!
