Aleph 3 with 4 output devices

[yasalam]

I have four matched IRFP240s and planing to build SOZ but after considering the cost I have changed my mind to Aleph 3. Since the Aleph 3 using 8 output devices, is it possible to use 4 output devices? It seems I must change the source resistor, but with how much resistant value?

Thank you for any response.

It's possible, and I would try .22 ohm resistors on the
Source pins only, leaving the rest as is.
