| Description |
No info available for this experimental UHF tube. It looks to be a planar triode, the octal base just used for the heater. The intermediate ring, believed to be connected to the grid, recalls the grid ring of WE 416A to D series. The threaded top hole suggests the presence of a screw-on radiator. Probably a low to medium power trasmitting tube for frequencies in the order of some gigahertz.
