RF Amplifiers



Below are some of the amplifiers I have built over the years.


Construction of RF amplifiers is one aspect of the hobby that I continue to enjoy. One cannot have too many amplifiers and as they say: "Life is too short for QRP!"


Needless to say: Please respect your licensing conditions and always practice SAFETY FIRST when working with RF and High Voltages.
