The 4X150D is a 150 watt, forced air cooled, power tetrode with a full rating frequency of 150 MHz that was first introduced by Eimac about 1947. The 4X150A is the same tube with a 6 volt filament. These tubes were later improved with 250 watt dissipation anodes and were redesignated the 7034/4X150A and 7035/4X150D.
