How to choose the correct value of the inductance for a choke loading anode in an common cathode stage? I suppose that this depends on Rp of the tube and on the desired frequency lower bound, but
HOW CAN I PRECISELY CALCULATE THE REQUIRED INDUCTANCE FOR THE CHOKE LOAD? Best regards.

Optimally (is that a word?), XL=(4*RL) at the lowest frequency you want to amplify.
Most designs use between 100 and 300H.

For -3dBV at F, L is EXACTLY (as you requested)
(Rp+RL) * 2 * pi * F / Rp * RL
For your purposes, pi = 3.1415926535897932384626433832795.

I know, I just couldn´t keep my mouth shut.
Sorry for that.

Ive seen XL=2Rp somewhere, but that might be a bit low
