Hi
I would like to ask a few generel questions regarding my upcoming re-cap of my dear sx-1080, and please forgive if they have been answered in other threads - I haven't seen them the places I have looked.
I have had it worked on a couple of times before. About 10 years ago it needed new main (22000uf) capacitors, plus some other components was burnt on the power supply assemply. Then about two years ago it needed some more repair (one lead-print on the board had broken loose at soldering point and was disconned, causing serious scratching).
During the past year I find that the sound quality has degraded, to the point where my CD-player in my car sounds better. More specifically there is total lack of treble, bass is OK, and I am hoping to regain the fantastic sound this unit has proven to provide.
I plan to renew the caps on the Tone Control Assembly.
Before I start I'd like to ask if anyone will share their opinion on this:
I am not deterred by taking it apart, if I have a safe way to connect the board-wires back.
Also I comtemplate to overhaul the tuner (left channel is weaker than right), but from what I have read here and there, it isn't trivial to do?
Best regards
Ole

Before I start I'd like to ask if anyone will share their opinion on this:
1) Having taking it apart, is it worthwhile to do a complete renewal of ALL component (resistors, caps, transistors) on the Tone Control Assembly board?
Same question for all boards? Some boards?

2) What is the best way to deal with the fact that boards are interconected by wires that are wrapped? I find it rather difficult to work on the boards, while they are connected. I don't have the wrap/unwraping tool, so the only alternative I see is to cut the wires and re-connect them by soldering. What is the right tinhg to do?
