Hi, I started recapping my Akai AA 1030. The unit was working perfectly fine, and I really loved it, so I decided to extend its lifetime even more - I bought myself Nichicon capacitors, a soldering unit, everything. That was obviously a bad decision: after recapping the two main capacitors, the ones from the power supply board and the ones on the main amplifier board, I started to have a DC component (7.3 V) at the loudspeaker output. I was so desperate that I put the old capacitors back as they were (and btw, they were all still good), paying attention to polarity, etc. Unfortunately still the same. I found the schematics of the device, unfortunately I don't know where to start from. I am a software engineer, so not quite skilled in electronics...I feel now so sorry for starting this in the first place. Anyone here could help?
