Description

Bias Mod Kits allow easy checking of output tube bias currents, regardless of whether those tubes are fixed-biased or cathode-biased. Included in each kit are meter tip-pin jacks, one bias pot for each output tube, the current-sense resistors, and extra grid-leaks and coupling caps as appropriate. Basic instructions are included. See our book, The Ultimate Tone, Vol. 2 (TUT2) for complete bias instructions.
