In Reply to: Re: Would changing amp power supply caps from electrolytics... posted by Mikenificent1 on May 20, 2000 at 18:53:27:
..Here's a picture of high grade polypropylene cap, rated at 50uF @ 100V(AC). A DC rated one would be about 10-20% smaller.Beside it is a high grade 4,700uF cap, rated at 63V(DC). I've included my Amanda McBroom CD, for scale. NOw, perhaps, you can imagine the impact of several tens of thousands of uF of filter capacitance. The enclosure required, would be huge. The wiring between the caps, would long and quite inductive.
To put the costs, into sharp relief, the cost of the 4,700uF cap is about AUS$8.00 each (US$4.50). The cost of the 50uF polyprop cap is about AUS$42.00 each (US$24.00). You get the idea? Figure on at least 40,000uF in a decent amp. 200,000uF, or more, in very good amps.
