Red Wine problems..

zivhackman · 12th September 2011, 09:25 PM

It’s the first time I post a thread here because I’m not into digital electronics at all..
But recently I started to hear a lot of distortions from one channel.
I discovered that the source of the problem is my “Isabella” DAC.
I ran some tests with my scope and notict that only after the DAC is well wormed up, one of the channels is starting to distort.
I can’t fined the source of the distortion in the analog circuit, and I’m pretty lost..
I would appreciate if someone would help me!

Thanks,
Ziv.

It would help to see a circuit if only to swap the analogue feeds over and "prove" which half (digital or analogue) the fault lies.

If the fault is consistent and does appear when warm then dripping (not squirting all over the place

) some freezer spray onto key components could very well find the problem.
