There is = little point in tracing DC past the PSU - if you have a stable voltage = there, a supply issue is very unlikely. You'll have to trace digital = signals (or, behind the DAC, audio)... >=20 > Sevo I only have an analog oscilloscope, and zero experience in such things = anyway, so wouldn't even know where to begin... The fact that there are = no circuit diagrams available for this beast exacerbates things too... Ugh. Dan=
