Aleph2 Transistor question!

JarreYuri · 20th October 2006, 01:57 AM

Hi everyone!

I am on the starting blocks of getting parts for the Aleph2´s.

NOW. I have seen that I should use IRFP240 for the outputstage.
That´s OK. But I have come across a big amount of IRFP460LC.
What would be the problem if I used theese instead.
And what would I have to change to make those work (if I even CAN use them in this amplifier).

The main difference is that IRFP460LC are higher in Ptot:280W, Vds:500V and slightly higer Ohm:0,27. AND they are much more expensive then the IRFP240.

Otherwhise they are the "same"...

Could I use theese?????

Probably you can drop them right in.

I can get 50 or so of these for next to nothing. Would they work for an Aleph 5 or 2?

Thanks!
