Re: My parafeed 300B prototype and questions
Posted by keto on May 19, 2004 at 18:55:50:
Its my understanding that parallel caps provide the sum of the two capacitances and half the voltage rating. If so, those 4 20uF caps will be equivalent to a single 80uF/165VAC cap. Maybe stack them series-parallel, to yield 40uF/660VAC, or put a dropping resistor between each. Looks like an intesting circuit. How does it sound and how do the two drivers compare? Is the 4uF coupling cap before the TFA2004jr rated for such high voltage? --keto
