Re: Ray, the whole point of using a choke input filter...

Hi Allen,

I understand your point. Since the main purpose of Satoru Kobayashi's PS design was to avoid the use of a heavy and expensive choke, I wonder if reducing the size of the input C before the MOSFET could help to minimize the spikiness to any useful extent? Or would a small inductor < < 1Hy before the input C, as proposed by Jeff and experimented with by Henry, help to neutralize the RF? BTW, did you find this to be a problem in your own PP-1C?
