Unitedradio.com is the only game in town for Eclipse manuals. A**rapers for sure. They are also the repair center for Eclipse.
I've owned/used almost all of the high end Eclipse decks and it sounds like your 8443 has issues. In EQ mode or Pro mode all 3 sets of RCA's should be working. The "fixed out" pair is full range, full volume, so don't tap into it unless you want blown speakers. No volume control on that pair.
P.S. I have a CD8443 manual, but I ain't gonna copy 133 pages for you //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
