Have you checked the prices on some of those? One I looked up was $109.67 each!
I will stick with the Simisouth power jfets!

Uh-oh! At this rate he's never going to get done with The Beast.

IXYS RF: HF/VHF Linear MOSFETs
TO-220/247, TO3P packaging probably limits FR
by using RF packaging and metal gate mosfets you could extend loop gain intercept and audio frequency feedback factor by 10X - assuming single pole compensation
of course I don't know why you'd bring that to Nelson's attention given his apparant lack of interest in high feedback designs

When I talked to experienced tube amp designers, they refused to think about using power MOSFETs because of their large non-linear input capacitance. Of course, an experienced designer could deal with any parts, but at expence of some compromise. What is proposed in this thread, is just a step towards less compromise design.
Seems to me you could build some major watts per cubic inch class D with those rf devices. The output choke would be so small.....

I figured I would ask in this post about some mosfets I found in the junk bin.
I have 5 "mega mosfets" IXYS IXTK62N25. I was thinking about Son of Zen amp, or balanced Zen light with these? I assume these can be used in a Class A amp and biased pretty hard. The ciss is high @ 6600pf I would assume thats the only limitation on this mosfet?
Thank you,
Steve

New exotic parts are coming out of the woodwork.
Wait a little bit and I'll have something really special.
