STC CV5298 / G55/1K voltage stabiliser

This valve measures 64x17mm overall and has a B7G base.

This is a miniature cold-cathode gas-filled voltage stabiliser for use in industrial and radio equipment where a stable source of voltage is required. The noteworthy feature of this valve is the relatively low maintaining voltage of 55 volts.

Note that the anode cylinder is not straight sided but bows in at the top and bottom.

The valve was supplied fitted into a 4-pin adapter suggesting this is used as a replacement for a larger type.

Operation with reversed polarity will damage this valve.
