RE: Plate chokes for 10k Rp type tube

Posted by shane. on December 6, 2016 at 22:18:30:

Hello MSL,

Thanks for the response, the application is the input tube of the attached amplifier schematic.

Rp is ~10k and the bias resistor in that stage carries also the filament current, the 18R value is correct.

I really needed as much HF response as possible, and I'm not sure that I really need the ~300H that the EXO-010 might present, with the info provided is it possible to calculate the in circuit HF limitations with what you have in mind?.

Need a pair of plate chokes for the driver tube as well, much simpler I'm assuming.. Ip = 20mA.. Rp of the tube is ~2k.

Thanks,
Shane
