GU74 Power Amplifier

HF-Power Amplifier with automatic Resonance Tuning


Details of the RF-Cage


My newest home made project was a Linear amplifier with automatic resonance tuning and two Russian metals ceramics tubes GU74. The Linear amplifier delivers 1200 watts of linear power from 3 to 30 MHz. A tuning of the plate circle is not necessary. This takes over the built-in automatic. A detailed description with all data and documents has appeared in the CQ DL issue 10 to 12 of 2008. Interested HAM's can receive documents also from me.
