If anyone has an Alpine 4913 that they're not using, please let me know. I'm trying to connect a CHM-S520 CD player to an early Alpine 7390 which runs the audio signal outside the M-bus cable. Instead of creating a new cable, Alpine used to sell the 4913 adaptor which converts the M-bus to M-bus + RCA. But I can't seem to find the adapter anywhere. If anybody has one, please let me know.
I haven't seen the CHMxxx changers, but the old 595x series signal outputs were very accessible. If your changer is similar, it may be simple to add an RCA output at the changer.
Likewise, it may be reasonable to jump the inputs inside the 7390 over to the DIN plug, if the pins are actually connected. That would save you a patch cable, but would be more cramped quarters to work in.
BTW, that's a very nice head unit. Good (500mV) preamp, tone controls at 30Hz and 20kHz. I could talk myself into one...

good luck with your search, i was in the same quandry a few months ago, i needed the 4913 to connect the cha-s609 to my 7909, fortunately i was able to find one locally
Have you taken the changer apart and tried to identify the oudio outputs where the din plug is connected to the board? I seem to remember that some of them were actually labeled. you could then solder a patch cord to the board and get it out of the unit to supply audio to the deck.
