TUBE OF THE MONTH THE EY500A / 6EC4


This month Thomas is highlighting another rectifier tube, but something quite different; a TV damper/booster diode. The EY500A is a contemporary version, that was used in color TVs. 

The EY500A has 6EC4 US designation and come as 6,3V equivalent of the more common PY500A/42EC4 valve. 

EY5400A probably have the highest ratings for peak inverse voltage and current delivery capability among all the TV dampers, with continuous current rating of a whopping 440mA for   a single tube.

In a full wave rectification two would be implement or four in a bridge arrangement, translation to double the current which can be drawn.
