Hi,

I bought some irf644's awhile back by mistake. Is it okay to use these for an Aleph 30?

The specs look very similiar to the irfp240 except the 644's are to-220 package.

Maybe there is some other parameter I overlooked that would allow these to be used in place of the irfp240's?

Thx
 
Thank you.
Most likely will not use them in this case.

I could not find further details for the Aleph 60 diy builds.
Is it the same circuit as the A30 just with more paralleled Fet's. Looking for the correct resistor values for biasing,etc...

I study biblical Hebrew ever so often, curious as to why you chose Aleph for name of the amps. Is there another meaning other than the letter A in the Hebrew alphabet? Anyway, it is the perfect name for these amps, Class Aleph :D
