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 also included. See our book, The Ultimate Tone, Vol. 2 (TUT2) for complete bias instructions.

Add the appropriate BMK to your SV1 or SV-TT Power Scaling installation to have control over the bias level of each tube individually or for each push and pull circuit half.

All our BMK kits come with comprehensive notes providing installation steps and diagrams, and adjustment tips.
