Sanyo CP-10 Rejuvenation
First things first, Sanyo CP-10 is not exactly"portable". Unlike Sanyo CP-12 and Sony D-50 it does not have theoption of external battery, it is one piece with its power supply. Also, it is exactlythe same CD player as "unobtanium" Grundig CDP-50, except that you canget CP-10 off ebay for $40-100. Hopefully Master Gu will add at some pointhis thoughts on why this Sanyo/Grundig is among the better-sounding players out there; belowis my story on how to rejuvenate this old lady:The end result, Sanyo playing audiophile-quality CD of apretty mediocre performance of Stravinsky/Rachmaninov:Once you open her up you see this:The flexible boards are actually SOLDERED to the mainboard(Service Manual presumes that you know this, well, I did not!). the end result ofbeing ignorant is breaking one of them:General knowledge (off youtube of course) tells you that when this happens, that's it. Here isthe living proof that with some patience, clamping forceps and epoxy, flexconnectors can be fixed. (photos of the procedure may affect younger viewers andhad been deleted). Once you get to the heart of the player you see a 30-yearold rubber belt for the sled, you Must put a new one here. The belts I bought some timeago for Sony D-5 fit perfectly! lucky...Since I went this far, to peek inside its laser is amust:B-e-a-u-t-i-f-u-l!!! Someone on Linn Sondek forum coined theterm "audioporn", this is it!Since only Master Gu knows how to align a new laser, we arenot touching anything here...new belt, fresh grease, a few rounds of +/-1 V DC to workthe sled up and down:One rubber grommet got "rigor mortis" and had tobe substituted for a piece of soft rubber tube (in blue), then everything isready to be put back together. Volume control was sprayed with DeoxIT, simpleand effective.One of the headphone plugs had been torn off, so it isreinforced with black epoxy and an extra bridge, then all flex connectors soldered back.Broken lid opener glued back with polystyrene glue and reinforced with A Lot ofblack epoxyI did not bother with taping wires to the board for thesimple reason that I cannot find that special uber-sticky tape used by SonyPCDP. ...if anybody knows please post here...The end result: Sanyo playinga pretty good "pressing" of myfavorite Genesis album:then gets new rubber bumpfeet, lid gets polished with"Novus 1-2-3"
Conclusion: very rewarding for the beginners like myself :)
Good job! Hope to see more of your restoration posts!
