This cabinet’s amplifier is a 2 channel tube type chassis with 2 x 6550 finals in the rotary channel producing 35 watts, and 2 x 6973 finals in the stationary channel producing 20 watts.
The 50C was designed for use with Conn organs, but like the other “Conn” cabinets, it can be attached to almost any dual channel organ with the appropriate connector kit. It cannot, however, be used with a stereo organ as the cabinet has one rotary channel and one channel speaking through a 6×9 stationary speaker.
This cabinet replaced the 50C and represents an advance in amplifier design.
