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 TUT2 for complete bias instructions.

Add
the appropriate BMK to your SB-1
or DC-PSK-1 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.
This page allows you to order the BMK6.
