DIY: AMB lab sigma 22 regulated power supply
« on: July 04, 2017, 10:56:10 AM »
We spent few hours solder two set of the sigma 22 regulated power supply from AMB lab. The PCB design is quite nicely done, but supplier have send some wrong value resistor parts , so could not done the measurement till we get the right parts. The circuit is quite simple and suppose quite low noise and good for audiophile application. Originally design is use to power their own power amplifier. Stay tune for our test measurement and listening test for audio...
