Up for bids is a lot of (3) Catham Electronics 5R4WGA Full-Wave Rectifier Tubes. These are ruggedized tubes, designed for severe duty and for very high altitude radios and electronics.   They were called potato mashers for their unusual base design.  The three tubes offered are from 1950's US Military production.  The tubes are used-each one tests good on my EICO dynamic tester and they show no shorts.  The tubes are clean and in good condition.  Catham Electronics was a division of Tung Sol back in the day.  If space in your equipment allows, this type could be used as a long-lasting replacement for the popular 5Y3G or 5Y3GT tube.   Used in power supplies of heavy duty transmitting and industrial equipment, this tube can handle up to 2800 Volts of peak inverse plate voltage and 650 mA plate current.   Each tube has a pair of large black ribbed plates.   I can see no flash getters on these tubes, but they could be down in the base and out of view.  Bid on these good, used, tested-good, US Made tubes for your own equipment or for use in future projects.   Bid on them "as is" due to age.  NO RESERVE!!  E-Mail any questions and please view my other listings. Multiple wins may be combined for shipping.  Thanks for looking.
