Wow - very cool schematic ! I wish they were all that big and clear. I'd say you'll have no problem at all using that power transformer. Start with the same basic circuit, then maybe trim the last set of dropping resistors so the driver board gets what it wants voltage wise. (R-203 and 204) Let us know how it goes - always some good answers on here too.

Hi NateDawg,

Let me know how your rebuild of the HF12s goes...I have a pair at home and had the same idea you have about building mono blocks. It's one of those projects that started out running on high octane gas and has been downgraded to diesel due to other projects...
