Just recieved the Complete Service Manual from SONY. Chips are
Mikinput = ADA 4841 - 2YRZ-R7
Lineinput = ADA 8662 2ARZ-REEL
AD Chip = AK 5358 AET-EZ
Thanks for the info.
I looked up ADA4841, this might be a useful chip for modders too, it comes in TSSOP/MSSOP, ie., the smaller size surface mount. Might be interesting for R4 mods, for example.
So, do you have any more information, like a schematic? I'm interested how the regular and -20dB mic in are handled.
