  • Notes
  • The model 02A made by Wells-Gardner & Co. was also used by Lafayette B-51 De Luxe and the various models up to B-59 called "custom built" - and also by Montgomery-Ward & Co. for model Airline 62-89. Caution: The anode voltage at the rectifier is 1040 volt and the loudspeakers do get 405 volt! The schematic for all 3 companies does not reveil a meter as tuning indicator but the model from Lafayette show one nicely integrated in the scale. Also the "sister model" from Wells, the model 022 (with tube 46 instaed of 45) does not show a meter. 3-gang tuning condenser, AVC rectifier and separate AVC amplifier, both are tubes 56.
