Amplifier build on GU-43B tube. Frequency range: 1,8 MHz up to 28 MHz. Input power range: 25 to 30 Watts. Output power range: 1200 to 1500 Watts. Smooth start, stand alone anode …

The GU-43B tetrode is used for wideband power amplification at frequencies up to 100 MHz in RF equipment. This tube is generally considered analogous to the 4CX1000. Cathode: indirectly …

This experimental design is capable of 1.5kW output throughout the range 1.8 to 30MHz, 5W drive delivering 300-400W. The input is "swamped" by the 50 Ohm grid resistor eliminating the …

GU43b's Cin is 100 pF, for its compensation L1 and TV1 were used. SWRin is less than 1.5 on 28 MHz and less than 1.2 on other bands. VD14+FU3+C28 - protection from HV pulses. FV1 …

the GU-43B, as all tetrodes, require a stabilized screen power supply, designed to also handle the negative screen current that can occur at low RF drive; the GU-43B socket connects the tube …

The GU-43B tetrode is used for wideband power amplification at frequencies up to 100 MHz in RF equipment. The GU-43B has similar characteristics to the 4CX1000 tube. Cathode: indirectly …

Measured with a Bird Power Meter, Model 43, PEP. Well regulated screen and grid supply for +ve and -ve currents as well as current limiting to protect the tube and minimize the IMD. It is …

GU-43B, GU43B, Q-1P/41, Q-1P/42. 1.5 KW HF Amplifier FRINEAR 1500. 1.8–30 MHz, Input 50 ohm SWR ≤ 1.2 (Passive grid system, PA0FRI's 1.5kW QSK HF LINEAR published in RSGB's …

For many years for DX & Contest QSO on HF I used GU43B tube amplifier, and it was very reliable. So I decided at 50 MHz to power on the same tube. For the circuit, switching, and …

Tube ГУ- 43Б or Röhre ГУ-43Б ID30982, Transmitting Tetrode, air cooled, and shown. Radio tubes are valves.
