The 4CX1600U is a coaxial base tube. You build the socket from finger stock and the various cavity parts required for proper operation. I have run one on 432MHz moon bounce for several years and can

To be clear, the 4CX1600U is completely unrelated to the 4CX1600B. It is a totally different tube requiring different DC operating conditions, and intended for use in cathode-driven cavity amplifiers

There is no socket issue as it does not use one. The base connections are cocentric rings and the tube is designed for UHF cavities. It has a tarnished reputation of having inconsistent gain from tub
