Interesting,
And here I thought that the primary reason many modern
amplifiers lacked heavy chokes was to save weight,
space, and cost. :-) Something like this would have
never occured to me. It's surely not mentioned in any
of the (albeit meager supply) literature I have on
hand.
What would be the symptom(s) of this problem? What
would it look like on a scope? Ringing??
Resonant-choke filter? I'm not 100% sure I understand
what you mean.... but I'm guessing that you're meaning
resonance with respect to the ripple?? Would you be
willing to elaborate a little bit please?
Many thanks.
