| Descripción |
UHF triode, 50W anode dissipation, mu 6. Oscillates up to 900MHz. Grid and plate are supported by wires that run straight through the tube envelope: this geometry made it possible to mount the tube itself at the center of a half-wave resonating line.
388A selected for operation at 900 MHz.
