In Reply to: Re: Hammond 193B and 193C. (plus 157J) - What is the significance of the self-resonance in both power supply and parafeed applications? Have you built posted by freddyi on November 27, 2000 at 20:11:46:
When used as a filter choke, the main frequency to be concerned about is 120hz (or 60 if you're a half wave freak). The "resonance" won't be much of a factor. Personally speaking, I wouldn't use any of these chokes as a plate load unless the plate resistance of the tube used was 500 ohms or less. I just thought I'd throw out that info if it would be of any use to someone.Also keep in mind these values were measured with 10Vac. The measured values can change significantly with level of signal input.
