The Type 1214-E is member of the Unit Oscillator family that uses a self contained power supply | The Type 1214-E is a member of the [[Unit instruments|Unit Oscillator]] family that uses a self-contained power supply. It is designed to be used with Type [[1661-A|1661-A Vacuum Tube Bridge] as a signal source. | ||
Other members of Type 1214 family are [[1214-A]], [[1214-D]], and [[1214-M]]. | |||
Like others in 1214 family the 1214-M uses a transformerless power supply. | |||
A single 117N7 tube contains the power supply rectifier and a beam power section as the oscillator. | |||
