  The ANP240B version has modified connection of automatic recording level and new potentiometers with the 4 mm shaft diameter versus the ANP240A with 6 mm diameter. The number of transistors has been reduced from 16 to 14.

  The main difference between B444 Lux (ANP240) and B444 Lux Super (ANP240A or ANP240B) is a function of the right large knob:   

  B444 Lux - manual recording level from radio or microphone

  B444 Lux Super - switch between manual and automatic recording level
