I agree. If 1 kW is enough then I turn on the amplifier with GU-74B, if 2,5 kW is needed then GU-78B. Remember at an output power of 1kW, the GU78B will need a power supply of 3 kW. The GU-74B will then require a 1.6 kW power supply :). 73 Jonas LY1O

A trip adjustable circuit protect the tube from destruction by G2 excess current. A detection circuit, insulated by opto coupler, watches G2 voltage presence and acceptable current, to send information into safety chain and front pannel. Circuit revision 5, made for tubes like 4CX-1500 or GU-78b, is adapted to G2 regulated voltages up-to 500 Volts.

Carl, The GU84B and the so called 4CX1600B are completely different tubes. Similarly the 4CX1600U / GS23B is quite different from the now extinct GU91B.
