The audio output stage is very efficient. It has its own power supply with a tube rectifier. It was designed by RCA in 1936. It was used in pre-war televisions. The same scheme is used in my receiver. The loudspeaker is suitable for a cinema hall. He is 32 cm in diameter.
I replaced the capacitors, low-power resistors, amplifying tubes and mains plug. In addition, I designed and 3D printed a mounting base for the electrolytic capacitor. Everything works. The speaker produces a pleasant sound.
