Re: 2nd QMX Build and it wont power on and an update on my old unit...


 

Hello Devan

The fact that it has noise along there, not flat-lined, indicates to me that the PCM1804 is probably OK. You probably have an issue upstream of that. Could even be toroid enamel... or mixed up windings on the trifilar transformer. But my apologies if you have considered this already.?
