Gyrodec Power Supply
Power supply for gyrodec turntable motor. Digital synthesized 50Hz sinewave from eprom, audio power amp modules used to drive the two motor windings. 67.5Hz for 45rpm option didnt work since the motor would not run that fast.
Maplin Mosfet power amp modules.
I note from this picture the transformer dated feb 84...it was then that I built a Crimson Elektrik power amplifier - the heatsinks are also salvaged from that construction. Feb 84..I was 15! I still remember the day I was putting it all together.
