In Reply to: The problem with large capacitors posted by JLH on March 8, 2007 at 05:00:00:
Hi JLH,Nice post.
Spelling is "transient" BTW, but the thinking and post wins the day, so lets not carp.
For 30 plus years, I used to think, if 50 uF is good, 100 Uf is twice as good and I'd load it up. Ray Moth wants to execute it that way, with a large final cap.
But I always knew from this Forum that there was a fraction of builders who liked small capacitance, but I never figured out why. You see, with more uFs, the ripple measured lower on my fancy digital Fluke DMM !! That had to be better. But its worse DYNAMICALLY, and in terms of transparency - as you put it. The high C power supply impedes the music playback.
But my audio friends like Dowdylama prefer 20 uF or lower albeit with high HY Ls, and Dennis likes 50 uF or lower with Low HY Ls, and there are MANY hep others out there who were "tuned into" lower C's. But yours is the first Forum explaination I've seen on this. And, the fact that you tried to express this is appreciated in helpful personally to me, and hopefully others. It promotes understanding.
Thanks JLH.

PS: Yes, my C1 and C2 became 40 uF Percy ASC's in Gregs 245 SE amp, used to be 100 and 200 uF round can oils.
