1960 Klemt Echolette, Model NG51. #19712First thing. I think it is a 1960 model, but am willing to be corrected if you know better. I do know it is pre the printed circuit version for the mid 60s, meaning of course that this one has the hand wired circuitry, which according to those in the know, is the classic version. These are the German answer to, the Italian Binson Echorec and Meazzis, the American Echoplexs, the UK Watkins Copicats. These were the most common ones sold in Australia and
