  • Notes
  • The Leutz Current Supply Unit Type L was designed to operate continuously without overload when feeding four radio frequency amplifier tubes at a maximum of 100 volts, one detector tube at 67 1/2 volts, three audio frequency amplifier tubes at a maximum of 200 volts, and one power amplifier tube at a maximum of 450 volts.  In addition to supplying the above "B" voltages, the supply also provides a "C" filament of 7 1/2 AC volts for the radio and power amplifier tubes.

    The Type L was configured as a half-wave converter if a single rectifier tube was installed (lower power), or a full-wave converter if two rectifier tubes were installed (higher power).
