I just looked, and I have several new-in-box 4CX1600B tubes as well as some sockets and chimneys. I **won't** sell them, so please don't ask. I will trade one or two new-in-box 4CX1600 tubes for an old Johnson Valiant or Ranger in good shape, or maybe some high-power components like large ceramic vacuum variables. I really don't want anything else, especially cash. 73, Tom W8JI W8JI@contesting.com
