i recently picked up a sony cdp-591,which dates from 1991-2...i found it in a thrift shop.it was dirty as hell somewhat scratched and dented on the top panel[perfect but dirty front panel] but at an "as is" price of only 3.99cdn it was just too cheap to pass up working or not...anyway i brought it home,pulled out the minor dent/bend in the top panel where something heavy had obviously hit it recently[probably on the way to the thrift store by the look of it],cleaned up the outside...it was clean inside and appears to work perfectly in every way,i've played probably 10-12 hours worth of cd's and cdr's through it without a single skip or any untoward behaviour..so yay! not a huge score,but a decent lookin and working cd player for the bedroom system and something to play with and mod for only 4 bucks!
sound is typical cheap sony...lacking bass and lower mids with not much depth at all..but otherwise very clear and detailed,it does get a few things right...alltho it needs work,i think it shows some potential to be at least better if not ever great...the output stage seems to be straight forward and based around a ne5532 output with a close by tlo82 possibly used for I/V???the actual circuitry on the underside of the board is a maze and pretty hard to follow....
does anyone possibly have a schematic for this model or even any closely related to it?i've searched high and low and can't find one,i certainly can't justify buying one even if i could find someone who sold them..i paid 4 bucks for this thing,i'm not sure i can even justify buying a cheap universal remote for it until i see whether or not i actually end up using it!any suggestions on what to do and what mods work best with these sony things are more than welcome as well...
