Hi guys
I recently got my hands on a PCE Duo which was supposed to be working, except for missing sound. I bought it and thought that a simple cap replacement would do the job.
After some online research I stumbled upon this awesome forum and after reading this thread, I was pretty sure that the system could be easily repaired.
When I opened it up, I saw that one of the previous owners already replaced quite a handful of caps around the 4558 amps. I got a little bit worried.
Long story short, I did a full cap replacement (finding a few additional leaky caps in the process), but unfortunately, the problem still persists.
I have full sound from HU card or CD (redbook audio, adpcm etc.), but it's almost inaudible, both on the AV out and the headphone jack.
What could be the cause of this?
I'm considering replacing the 4558 op amps. Could that work? Or does the current problem suggest a different approach/solution?
