Transformer coupled (Sowter), front and back, balanced gain stage, valve rectified, choke regulated power supply.


This design was started when I was asked for the “Best preamp you can make” So this is it. There are some test results available, but the real magic is only heard. It is something special even though I say so myself.


I fully intend to build another (if only for myself) and will probably use a torrid for the power supply which will allow the power unit to be in a matching 4U non ferrous enclosure.


As to the name, well, thats what its owner wanted, he may explain one day.


To replicate it will cost their new owner £2500, but I have not heard any other preamp that can do what this does.
