I do not know why but I prefer simple, low power triode designs. May be it's the warm sound produced by these tubes or because I like horn speakers and I know that this relation is erotic. It's a kind of magic, a sweet sound triggers up your feelings, that can reproduced only from a combination of a DHT tube amp and a pair of horn speakers.
So last year I decided to construct a low power SET based on 2A3 tube. I had no previous experience on this specific tube, and this is something that excites me.
While I was looking for the simplest SET design of a top notch Valve amplifier that is based on a 2A3 DHT (Direct Heated Triode ) vacuum power tube, I came upon the "Loftin-White" circuit.
