I can't seem to find the IRFP240 locally. Would any of these work in the SOZ instead of the IRFP240?
IRFP254
IRFP350
IRFP360
IRFP440
IRFP450
Thanks for your help.

BrianGT,
This is an often talked about topic. You could probably search for more info. But, ideally, you want lower voltage types, like 100volts, maybe even lower if your rails on the SOZ are low voltage. The reason for using lower voltage types is a better distortion figure. Look for high wattage dissipation and high current capability. Better than 10 amps would be good. This ensures longer life.
Case type plays a roll too. Metal cans are good TO-3 or TO-247's. The TO-220's usually dissipate less, but are good for lower power apps. For the SOZ, it's best to stick w/ TO-3's or TO-247's
You proabaly know most if this.
Most are over kill, I checked all at WWW.DIGI-KEY.COM. The IRFP254 is probably your best bet. It will definitely work.
IRFP254-ND Price $6.20 US.
Description: HEXFET (N) 250V 23A TO-247AC
Good Luck!

Hi,
I replaced them with IRFP 3710 with a great sound.
I can compare them with tube amps and a hiraga le monstre.
Nevertheless i will try the original 240`s soon.

Hi,
I've tried an IRFP140 instead... It worked. (that's actually all i can say about it.. )

I think that I will try the IRFP254. They are $1.88 each at the radioshack.com, since all components are 60% off and they have decent stock of them. Would they work in a Aleph 4 design?

By the way, that is not the online price, just the instore price, since the 3 radioshack.com stores are going out of business.

also tried IRF540
hi
i've also tried IRF540 in a low power version (+/- 18V rails) with excellent results.

in ZEN variations irfp150 works well, and costs in germany about 2,50E each. IRF has very good datasheet information : http://ec.irf.com/ec/adirect/ir?cmd=search&query=irfp150

Hi,
I followed the advise of a member of this group (I can't remember which thread) and purchased my IRFP240 fets from Future Electronics on the web. I paid only $0.98 each when bought in lots of 125.

Sorry, I don't write thread for substitutes IRFP240 My thread is the ID=700MA,VGS<0.1V,the best VGS<0.01, So I use
IRFP250, I buy 20 IRFP250,the VGS from 3.93V-4.54V,
I control VGS difference at 0.04V.
You Can try.
