Default ps cap significance

Howdy guys,


I've had lots of experience with cap quality in push pull class a and ab amps, and how it makes a difference.


Has anyone tried Nichicon muse or Elna Silmics (or any other audio grade cap) with a SOZ and found a considerable improvement?

I ask as 100,000uf of audio grade cap is rather expensive, at the point where multiple optima batteries would be a better shot


Thanks for anyones input,


Mark hathaway

The nice thing about a balanced class A amp like the
SOZ is that it truly draws constant current from the
supply, regardless of what the signal is doing, and so
it is much less sensitive to the impedance offered by
the power supply.

Having said that, the large current drawn by the circuit
constantly does work the capacitors and everything else
much more than they are accustomed to in an AB design,
and you must allow for quite high ripple currents in the
capacitors, along with some fairly large values to keep
the ripple voltage down to a reasonable figure.

Cool planning on large caps

Thanks for the reply nelson,


I'm planning on 100,000uf per rail with appropriate slow turn on.


Just got to find some schottky's that fit the bill now. Probably will use a motor bike radiator for water cooling, going to shoot for something in the 25w area, doing 4 mono blocks for a bi amped setup
