My favourite power amp:
I have built many tens of power amps, but this is the first one I've built a second pair of.
(Actually I have had NCC200s twice, but at separate times, trying to figure out what all the fuss was about).

Now that I have the 2nd pair up and running I will be able to experiment with different configurations to try to further optimise the sound. However, my 1st set, built as a simple stereo amp beat all my other builds with separate/regulated/choke-fed/dual-mono etc. so I think it's fairly power supply agnostic.
The eagle eyed might spot a couple of caps missing - that's deliberate, part of my experiments.
As well as sounding very good it's rock solid in terms of bias stability and phase margin etc. and it has SOA protection. It doesn't use any exotic parts, although the 2SB/SDs are getting harder to find.
PCBs, BOM and documentation are all available. IIRC I got 10 for about £12 from PCBWay. The layout is technically excellent but just a bit cramped for component stuffing.
Recommended!
