Coma,
are you aware of the difference between AC voltage and DC voltage.
It looks like post300 is referring to DC voltage: Is "this amp is suitable for 4ohms"?
Yes, with 60-30-0-30-60v dc rail voltage.
and
post301 is referring to AC voltage: "I have 48-24-0-24-48 Transformer"

Your posts stating ambiguous voltages do not show whether you understand or not.

For 120W at 8E you need transformer 45-0-45 vac and you can use amp from this thread with 2 output pairs IRFP240/IRFP9240.
