Powerful Tetrode GU-39B-1 is released Russian industry and is intended for use in stationary HF transmitters by power before 13 kW. This be modern powerful tube has high reliability and longevity >2000 hours is guaranteed. output power before 15-20 kW peak CW or SSB with best linearity of reinforcement. The Anode load of tube is realized without problems before 30 MHz having low Roe<300 omm. The Tube works using current,similarly semiconductor! The GU-39B-1 Tube is used without socket. The Tube has two short copper conclusions of Grid and two long copper conclusions of Cathode. The Screen has the contact on copper ring.This tube works in vertical position with anode adown.Transformer for incandescence of cathode is situated near by tube and connection the copper buses with conclusions of cathode.Mechanical fastening can be most uncomplicated. PA on this tube need in addition 400W only for heater.Rest power supply is standard for all powerful tetrodes: GU-84B,GU-78B e.t.c. Only maximum power can correspond to your dreams and home power supply. Under 3-phase transformer for power supply of anode - no problems! Three wires on 20 A presently there are in any house. And this around 20 kW the power supply! With PA on GU-39B this 10-12 kW out. With high linearity of reinforcement. This tube is long-work and beside my friends on contest-station already works around 7 years in all contests. This be GU-39B-1 tube is used in amplifiers of class AB1 and AB2 in grid-driven mode. The Input power before 50W usually enough for 10-15 kW output! This tube is developed and applied in stationary 10kW broadcasting ÀÌ transmitters. The manufacturer inserts into new tubes the copper anode coolers from used FREQUENCY RANGE: before 100 MHz Max. Screen Dissipation: 450 W Max. Cathode current (Ic): 20A Screen current: 22 mA, max-150 mA Transconductance at (Ua=3.0 kV Ug2 =1.0 kV Ia = 2 A) : 25 mA/V Capacitance Input /Output /Feed-through :80 pF /29 pF/0.7 pF-max Designed Tube Life: >2000 hours Blower : 500 m3/h under 10 kW Anode Dissipation Operating Position : vertical,anode to down Output power can correspond to your dreams and power supply ! All tubes is packed in factory box and has the individual number passport. This sale is for ONE GU-39B-1 Tube New in factory box. (please look at our rules and privacy policy) |
