SET Driver comparison

Post by Naz »


I recently got into a discussion (or argument depending on which way you look at it) on SET Asylum regarding which of these two circuits is best as a SET driver. I'm posting the ASC file here for ease of access and for anyone else who may be interested.

I tried to set equivalent operating points for a fair comparison. Comments invited.

Active Load SET Driver.asc
My suggestion but including cap coupling for the sake of the exercise. I prefer DC coupling and I think it sounds better with drive taken from the plate of the bottom tube.
