Make a pair of 1969 Amplifiers (John Linsley-Hood). Copy a Chinese copy.

How to copy a Chinese copy.

In this video a PCB image is downloaded, scaled and printed to the actual size. The holes are then drilled and traces drawn by hand. The PCB will accommodate any size transistors, in this case I used the TO-3. I am impressed with the quality of the sound. You will need a bigger heat-sink and speakers. I ran the circuits on 12V but you could use 27V.
