Lovely builds. Wish I could commission you to build one for me. 🙂

My last Holton build is an 800L.
Modushop 5U 500mm chassis. It mabye oversized, but it gives me romm for some extra bias 🙂
2 x 750VA 2x55v toroids. Holtons PSU-Three with Elna 10000uF 100volt. And ofcourse the PowerOne 3.0 board.

Corner sub is Ficar IB18, 2 for each side.
Al speakers are dipole !
