I thought I was over Class D builds. But one guy as me to build one and another, who I’d already built one for, wanted another because he lost everything in our Xmas bush fires period. The second one I’m charging parts only because it’s my way of giving for those who have lost more than a stereo system.

These are RAW builds because it is just Tranni and hifimediy T4 180W amp module. No external PS. There is a high performance PS on board. One gone and the second one with a tube preamp also.

Yet another RAW style 180W Class D. This time a true integrated with a tube preamp. I have purchased four Radi0kit PSs (required assembly). These produce regulated 12V and electronically smoothed 250V . Tranni included for what it cost me to make mine from scratch. Mine takes four days I can build two of theses in an afternoon.

Apart from occasional very audible “crack” sounds (now attempting to fix) the amp plays well. Too much gain so I have cut away Ck. The amp goes down easily to 30hz. About the limit of my woofers.

Amp in the bottom right hand corner in a 2U. Quite sexy.

Some additional images. Also I have replaced the tube PS to see if this fixes the Very rare ‘click” sounds. Called the amp “Succinct II”. The guy I built it for had my original Succinct which I built for him on commission. By accident I found out he lost everything (more than his hifi) in our latest bushfires.

I contacted and said I would build him another for cost of parts only. He added the tube preamp idea to make it an integrated and I agreed. There would be no cheaper way to get the too. Compact also as you can see by the images.
