Extras ▼

 

The 6807 is a hydrogen thyratron and probably dates from the 1960's.
The data says that the peak inverse voltage (PIV) on the anode is 1,500 Volts maximum. The average anode cathode current is 6.4 Amps and the peak cathode current is 80 Amps.
The disc seal construction shoes the anode at the top and the grid connection ring below. The tube in the lower glass section shields the filament.
The view above the base pins. It is not clear if the central white cylinder is the cathode or an insulating sleeve.
The anode connection.
In this image the slots in the grid ring can be seen and the shape of the anode as a flat bottomed cylinder is seen.
This image was taken from an ebay advert and shows the other thyratrons that the type 6807 will replace.
The wide glass tube envelope is 67 mm in diameter, and excluding the base pins is 211 mm tall.
