Aleph P1.7 output capacitance question

Adams_Leo · 21st August 2006, 03:44 PM

Hi Everybody,
I am studying the aleph p1.7 service manual and plan to clone this preamp.I want to know why this preamp use 3pcs capacitances parallel connection in output,in order to match the amplifier low impedance? I am not sure.Anybody know.pls give you advise.

Regards,
Leo

I also saw this question via Email, and gave the wrong answer -
the right answer was that I wanted 30 uF and 10 uF is a
convenient size.

Nelson, were you at all interested in improving high frequency ESR with the caps in paralell. This might create a situation where the 3 are equal to a more expensive 30uF. Just my initial thoughts when I first saw that
