Hi Guys
Yes, any time fixed-bias is present the Power Scale solution includes SV1 instead of SV2. Having switchable bias modes in the amp is very easily dealt with using a SPDT switch with grounded wiper, one end to the top of Rk and the other to SV1 J1-1, If there are individual Rks, add more poles to the switch to shunt them when in fixed-bias mode.
Have fun
