Klitzing Amplifiers

In the late 70's, I manufactured and sold a line of solid-state linear amplifiers designed for the weak-signal enthusiast. Occasionally, I'm asked for information on these, so for those of you who may still have one, here is all I have left (the schematics for the most popular ones):



2 meters, 3 watts in, 50 watts out, first -generation (non-microstrip) designed for the IC-202 ssb radio and the 2-3 watt HT's of the time.



2 meters, 15 watts in, 80 watts out, first-generation (non-microstrip).



2 meters, 10 watts in, 100 watts out, the second-generation version of the 2M15W80



2 meters, 10 watts in, 180 watts out, second-generation.



70 centimeters, 10 watts in, 50 watts out, second-generation.



70 centimeters, 10 watts in, 110 watts out, second-generation.
