This is my home made stereo tube amp working, playing the song from iPod.
I built this stereo tube amp using 2 tubes ECL85. I also included a jack for ear phones. The ECL85 tube has a triode preamp and a power pentode inside the same glass tube. My circuit works on A Class (single ended) output and outputs 4 watts per channel of warm sound and good bass. I decided not use any negative feedback to preserve the 2nd harmonic distortion.
