IRF 230 or IRFP 140, what's better for AlephX ?

[RichardJones]

IRFP140N

I am using those in my Class A amp.

Running 2 per channel ... one as CCS other as follower.

from a +12 -12v battery supply... at 3.2A bias.

Sounds good to me.

NO SS artifacts. very neutral top to bottom.

love it.

I'm using those too (IRFP140) in my Aleph 5 and they sound beatiful. But I have a lot of TO3 IRF230 ready to use as well.

what was the pricetag (Peter Daniel) on the IRFP140(N?)??

The reason is that i was talking to a distributor about IRFP140N and IRF3205( Check this one out!!! gfs = 44S and .75degress/W)

And they gave me a unit price of 1.7$

Considering the Gate capacitance and Gfs, IRFP260 or IRFP264 should be a very good choice. What's more, due to its high Pd of 280 watts, you could run it of a slightly higher voltage, squeezing out more power, while the entire sound spectrum should be very balanced.

A second choice would be the IRFP460 - would be more solid in the bass region.

I paid CAD 276 for a hundred. Compare IRFP140N at CAD 212.

Thanks... I was just checking up on the price to see if it was okay!

Pretty close on the 100 pcs price i got. -10CAD for 100 IRFP140N
