Double diode triode

The term "double diode triode" is not standard in electronics, but it seems to refer to a vacuum tube or thermionic device that combines the functions of two diodes and a triode in a single envelope. Here’s a breakdown of the components: 1. **Diodes**: A diode is a two-terminal electronic component that allows current to flow in one direction only. In a vacuum tube context, a diode consists of two electrodes—a cathode and an anode.
