Hi Vostre
There are three options for having individual fixed / cathode bias switching control for each tube
1 - Use a separate DPDT for each.
2 - Install the relay type listed in the PA66 notes, then use a simple SPST or SPDT per tube. The relays mounbt on the board directly.
3 - Buy PA66-S2 which provides two relays and two switches, as required for each PX66 card (the power tube portion of the PA66).
Have fun
