50 MHz GS35b Power Amplifiers

 

The Russian VHF triode GS35b, is rated to operate up to 1000MHz, with 1.5kW anode dissipation. Considering it's low price, and availability I put some effort, in the development of a powerfull, and compact amplifier with the GS35b, for 1.5KW ++ output power at 50MHz.
