Description
EIMAC 8172 4X150G Used but in good working condition. 8HWG6367 ** FREE SHIPPING ** Manufacturer's Data: The 8172 is an extremely compact external-anode tetrode intended for use as a radio frequency amplifier, frequency multiplier, or oscillator at frequencies well into the UHF region or as an amplifier in any service requiring a high gain tube capable of delivering high power output at low plate voltage. The combination of a high ratio trans-conductance to capacitance and a plate dissipation capability of 250 watts makes the tube an excellent wide band amplifier for video applications.
