How to connect DIYHFS & DIYHS

How do you connect the Ultra low noise filament supply en de active bias supply module together on a push pull 300B amp?
In Short terms what is the correct way?
Can i just connect the filament supply to the tube and put 10 Ohms from one end of the filament (Cathode) to ground and measure over that resistor?

Is it possible to use one filament supply for 2 tubes?

You can connect it just as the attached schema shows. I think it would be better to use a pair of the filament supplies because running two 300 B. filaments from one supply would be right at the limit and would require an awful lot of heat sinking.
