4 Pin Bayonet, New Manufacture. - This socket is intended to be an exact replica of the Johnson 123-0210-001. Other dealers sell similar sockets of poor fit and loose tolerances. We worked with a manufacturer to get the highest quality form and fit possible. Fits any standard 4 pin tube with a locator pin on the side. Great for types 10, 50, 300B, 811A, 572B, 5557 / FG17 etc.
