Circuit diagram of the first version of the Pilot Little Maestro, the pre-war model. The second version is similar except that the mains line cord has no dial lamp tapping and supplies the valve heater chain only. Separate series resistor to the anodes of the 25Z6G rectifier. Frequency changer valve changed from 6A8G to 6K8G.
Later version 2 models have a PM loudspeaker and the field winding is replaced by a 1.5Kohm resistor.
