Im thinking about making a circuit using a DHT Pentode, feeding the filament with a regulated voltage and also use a constant current source to bias the tube.
the voltage source gives filament voltage and the current source is set to source filament current + bias current.
is this the right way to think when doing a CF this way?
will the current source deal with the bias by its own or do i need an additional resistor?
here is a scetch of how i think it works like. the tube is not the actual one i have in mind...
