Up for sale here is this NOS vintage Amphenol black UX7 (U7A) 7-pin tube socket, with attached mounting plate.  This is a NOS unused socket. It is still sealed in the original US military package, and is guaranteed to work great for you.  This is a UX7 7-pin socket and will fit a 6B7 tube or any other UX7 (U7A) tube.  It will not fit the larger U7B base tubes such as the 6A6.  Please see my pictures for details.

US shipping and handling is $5, and international is $18, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. If you have any questions, please ask.
