Power Tetrode
The 4X150A / 7034 Vacuum tube is a compact metal tube. It is intended for use a an amplifier, oscillator or frequency
multiplier at frequencies up to 500 megacycles. The 4x150A is designed to operate with a heater voltage 6.0 Volts,
whereas the 4x150D is designed to operate with a heater voltage 26.5 Volts. Otherwise the two tube types have identical
characteristics.
