I was impressed by reports of persons who had built them, so I've gone and built a pair.
I was helped by dismantling my Pass 50W mosfet amps, so did not need to buy much extra, and the (now voluminous) spare parts box contributed as well.
I was helped by a friend (yes, I have got at least one) who had a pair of the printed circuit board and two MOTs (microwave oven transformers) to use as the chokes.
End up, it's the best amplifier I've ever listened to in my house, so hugely well pleased.
