Dead DAC
Posted by JRMA on December 18, 2020 at 18:49:28:
So I took a chance on a craigslist ad. Almost free. CAL Audio Labs Sigma DAC sold for parts/not working.
Went through it looking for any obvious problems. Checked voltages at test points, heater, plate etc. All good but still no output, no digital lock.
Anyone have any idea how to troubleshoot this classic DAC?
