This is the best amp which has output under 2W that I have ever made. Using 71A tube, para single end amplifier. Driver tube is C3g, rectifier tube is 83, can be changed to 80. No NFB was used !

71A tube is excellent tube for audio, it is same as 101D, 102D , which is very musical and beautiful sound, but it has low output power so it is very difficult to make an power amplifier with 71A as output tube. An single end 71A tube can procedure max 0.8W, this amplifier use 2 tube in one side Para SE schematic
Sound is perfect, very beautiful and detail with rich sound. It is really amazing sound with only 2W of output.
