Capacitors, coils, switches, and more... more... in my e-Store The GU-74b tetrode is used in wideband nontunable amplifiers and for single-sideband power amplification in stationary and mobile RF equipment. It is useful at full ratings through 250MHz. The GU-74b tetrode is generally considered to be similar to the 4CX800A, although some users report that it acts more like a tube having 900 or 1000W anode dissipation. Cathode: indirectly heated, dispenser, oxide-coated. I - contact surfaces; 1 - grid 1; 2, 4, 6 - cathode; 3, 7 - heater; 5, C2 - grid 2; A - anode ENVIRONMENTAL OPERATING CONDITIONS Multiple impacts with acceleration, m/s² Relative humidity at up to +35 °C, % Mutual conductance (Va = 1KV, Vg2 = 300V, Ia = 600mA, change in Vg1 = 2.5V), mA/V: Anode current (Ia) with Va = 2.5KV, Vg2 = 300V, A: Negative bias (Vg1) with Va = 1KV, Vg2 = 300V, Ia = 600mA, V: Negative cutoff bias (Vg1) with Va = 1KV, Vg2 = 300V, Ia = 15mA, V: output capacitance, at most, pF AB1 Output power, Va = 2KV, Vg1 = -60V, Vg2 = 300V, Ig2 < 50mA, Freq. 0.1-1.0 MHz, W: 3rd-order energy relative to carrier, Va = 2KV, Vg2 = 300V, Ig2 < 50mA, Vg1 = -70V, dB: 5th-order energy relative to carrier, Va = 2KV, Vg2 = 300V, Ig2 < 50mA, Vg1 = -70V, dB: Maximum CW Anode voltage (Va), KV: Maximum Instantaneous value Anode voltage (Va), KV: "Maximum" Control Grid voltage (Vg1), V Maximum Screen Grid voltage (Vg2), V Screen Grid (G2) Dissipation, W: Control Grid (G1) Dissipation, W: Curves for this tube are being prepared for presentation, four (4) yet to be added (as of 6 June 2001)!
