Available for purchase is a Trilithic SSR-9580 Return Path Tester.
I am selling this as parts or repair with no returns due to my inability to test it completely.
It has been tested to power on. This item is in very good condition and has very minimal signs of handling or use.
The battery will take a charge but I can not guarantee the battery life.
I have a few of these, the item in the photos may not be the one you receive.
