Excerpt from An Electron Tube Transmitter of Completely Modulated Waves

In all three figures T is the 5oo-cycle supply transformer fur hishing the alternating plate voltage and C' is the total effective capacity of the oscillatory (antenna) circuit.

Fig. I (a) shows a direct-coupled circuit with parallel power supply. The secondary of the supply transformer, T, may fur nish a sufficient choke for the radio - frequency plate current. In some transformers the distributed capacity of _the secondary winding is so great as to by-pass the radio-frequency plate current, and a radio - frequency choke coil must be inserted in series with this winding. C is a stopping condenser with negligible radio frequency reactance; it should be noted that it is possible to ap proach soo-cycle resonance in the circuit formed by the secondary of the transformer, T, the condenser, C, and the plate coupling inductance, causing an alternating voltage to be applied between plate and filament much higher than the secondary voltage of the transformer. This condition may be, disastrous for the tube if it is not taken into account in determining the transformer ratio.
