Irfp260 is better than irfp250.... 260 have low Qg and support more current.... why you don't use that?

IRFP250 from Harris Semiconductors..

what load did you test with the irfp250 at that voltage and the switching frequency , also how long did the amp play .
Hi stewin,
My AUD600 still running on theater as a sub woofer, connected load 2 x 8R(650W) 18" parallel
supply rail +/-87V (90V) tested on idle full drive +/-82V (900W RMS)MOSFET Used IRFP250 Filter 33uH T157-2 both are running cool

I don't recommend any of these, they are weak. BC807/817 are better, and FMMT549 is very good. (NPN can be weaker.)
Yes, BC807/817 or FMMT549's current is larger, and the driving power is greater.
