The ZP-1074 is a UHF triode made by GE. It was rated at full power to 425 MHz and usable to 1300 MHz in pulse service where it had an output of 40 KW. It seems to be a developmental or special feature version of the GL-51074. The second example has a different coating that is possibly to allow liquid cooling.
