In Reply to: Is there a sonic benefit in bypassing electrolytics in power supply? posted by Eric U. on July 13, 1999 at 18:52:07:
If your talking about bypassing them by taking them out of the circuit, expect horrible sonics. If your talking about "bypassing" by placing smaller caps in parralel, you can expect sonic benefits. This can help some amps by cleaning up sibilance, hard / hashy highs and treble smear.The smaller caps can discharge faster than the larger caps can and would respond to short term transients much better. This is an old trick and very worthwhile if your amp seems to suffer from the aforementioned problems. Sean

Bypassing is actually the correct and commonly used term, although "paralleling" as you put it would not be an inappropriate term. The film cap is bypassing the electrolytic in the sense that it is allowing the delicate, vulnerable signal or portion thereof, to bypass or go around the sonically "bad" electrolytic. Ever since the early days of the tube amp, the caps hooked up in parallel with the cathode resistors of small signal stages were called "cathode bypass condensors."

But since we're talking about bypassing electrolytic caps in the power supply, I'm really confused. How does the current coming from the rectifier know that it is supposed to handle the "delicate, vulnerable signal" portion and hence go around the electrolytic and through the film caps on its way to the circuit board?
Just wondering.

Is there a value guidline that you know of ( i.e. 1% of PS cap value? ) max or min?Thanks
