Description This tube has three electrodes:
A filamentary cathode, a helical anode at high potential and an outer cylinder called "3rd electrode" kept at a lower potential.
The secondary electrons bounced back from the 3rd electrode are collected by the anode. The Dynatron behave as a true negative resistance device.
