Gs35b Amplifier. To date this amp is still in Contests operation. Originally design

To date this amp is still in Contests operation. Originally designed as power triode for UHF Radar applications it has a plate dissipation of about 1500W. The "medium GS-35B 2,5kW Power Tube! With 4kV on plate >3. In 2003, I decided to build another amplifier with GS35b HOMEBREW 50MHz AMPLIFIER POWER SUPPLY CIRCUIT DESCRIPTION The power supply used is a converted ETO MRI supply purchased in Dayton 2005, which is really 2 power supplies in one. 95A Maximum CW Anode voltage -4. Power outpout is 1100 watts. 0 kW can be expected on 144MHz in a grounded grid amplifier! Intermodulation distortion of the 3rd order - minus 32 dB. It is built to last and provide many years of reliable service. The "high" voltage side of the supply is built around 11 Mallory filter capacitors at 2,200 uf each with 6 equalizing/bleeder resistors (R6-R72) across them rated at 220,000 ohms at 2 watts each. It covers 160 through 10 Meters. 50 mhz 1500 watt russian gs35b amplifier well documented complete construction details pictures schematics and more . HF and VHF". GS35b 6m Amplifier Here are some pictures of my GS35b amplifier for 6 meters I built back in 2005. This amplifier is designed around the low cost Russian GS35B triode, and features: 1. 90W drive delivers about 1500W output. This amplifier was designed to run 24/7 key down for heavy contesting and high duty cycle WSJT modes. Anode compartment GS35B 50Mhz amplifier by G0RUZ This amplifier offers nothing in the way of original design features but draws on the experiences of others. At the time, I was inspired by the realization of our friend Daniel F1DRR (SK) with some modifications. KW i UKW" magazine in Belarus. Listed under the Technical Reference/Amplifiers/VHF Amplifiers category that is about Amateur linear amplifiers. The GS35B is an extremely rugged and reliable tube and will produce 1500 watts output with the typical 100 watt 50 Mhz . This can be done in many ways such as lowering the grid below the chassis using tubular spacers. The amplifier described here is an update of the High Power linear amplifier described in the July, 1995 issue of the "Radiolubitel. The output network is a Pi-L to suppress the second harmonic and a T-network is used for the input. The GS35b is a Russian triode that is relatively cheap and easy to get hold of. 0 kV GS35b HF Linear Amplifier Having been successful with my 813 amplifier I have now decided to take things up a gear and build something even more powerful. The author, EW1MM Gary Podgorny (callsign in the 1970’s was UA6LFC) constructed his 1st high power amplifier in 1976 using GS-7B metal-ceramic triode (see the black and white The system employed in this amplifier spaces the tube below the amplifier chassis in order that an air flow can be created around the cathode and grid seals. It uses the standard cathode driven grounded grid configuration. GS-35b tube power amplifier Specifications Сomments This is super powerful amplifier build on GS-35b tube which characteristics are: Intermodulation distortion of the 3rd order -minus 32 dB Anode Dissipation - 2. 5 kW Grid Dissipation - 26 W Cathode- Oxide coated Heater voltage - 12,6V Heater current - 2. GS-35B Amplifier For 160 Meters Built By Bob Briggs, VK3ZL This "Home Brewed" Amplifier uses a single Russian GS-35B Power Tube and has an output power of 1. Please note: This unit is not the current Linear Amp UK amplifier available from Paul G4KTZ Click here for my home brew 50mhz GI7b amplifier The following information covers the 2005 model of the commercially made 'Linear Amp UK' GS35b amplifier for the 50mhz band. 5 KW. The Linear Amp UK GS35B 6m amplifier As built by Peter Rodmell, G3ZRS. 5KW output using grounded grid circuitry with about 100 Watts drive A commercial (expensive) tube socket is not required Easy to fabricate low cost air system chimney Fast vacuum relay T/R switching Variable cathode bias to accommodate various operating conditions Tube protection circuitry helps prevent damage GS35b_F1CXX Last update J GS35B HIGH POWER LINEAR AMPLIFIER FOR VHF/2M/144MHz DESIGN and HOMEBREW by F1CXX I realized in 1976 a 144 MHZ amplifier with a 4CX1500b. In English, this is "Radio Amateur.
