Some one said RCA 71A arquitecture is very similar of RCA50.
many audiofile like sound of 45 single ended amplifier.45 made good sound on high range
frequency but low range is not enough.
71A single ended amplifier sound is just like 300B sound at high volts use. 71A single ended amplifier
makes around 0.7 W rms. but enough to use at home with over 91db/m/w speaker system.
What do you think ?
