Testing 71A Tube Amplifier. Just 0.7 watts. Valves originals from 1927.

Single Ended Triode Amplifier 71A with 0.7 watts power. In driver valves Arcturus 127. Made by Oliver Sayes in New York around 2013.
I really like this valve, one of my favorites. And I like with Electronic Tech House Music as well, like this.
Testing after 8 years in a warehouse. Trafos were changed for japanese ones taken from an Akai M8 reel to reel portable amplifier.
Not the best amplifier but enough good to enjoy the music.
