Need a new transmit receive relay for the original Texas Star amplifiers and many others used from the early 1980’s through the mod 2010’s? These are equivalent to the original Potter-Brumfield open air relays used but better as these are sealed. These are also 5 amp contacts but specs show 7.5 amps @ 28vdc. We ship out ten days or less due to our Monday-Friday travels. No implied warranty, guarantee, returns or refunds but will do our best to make it right
