Re: Ultrasonic AC for DHT Filament

Thanks for the tip. In fact, I recently just purchased some chokes for two different projects, a tubed output SACD player, and a modification project for a Cary Phono pre. I did pick up two filament chokes for each. I will implement as you suggested with the capacitance between the two. I will have to go back to revise my SE amps though.

One question, is the voltage drop through each of the filament chokes simply the amperage times the DCR of the choke, or is it different because of the residual ripple?
