We need those kind of goodwill junk stores in here. Sites like OLX have expensive junk with devious sellers... Last time I repaired a shelf cd-player, it was a AKAI. This AKAI was a basic cd-player with only analog output and no amp. It had a problem.... a broken cd tray belt. I cracked opened it unscrewing 5 rear screws and 4 side screws. I had to unscrew the cd reader part and remove some attached cables to the logic pcb and remove the top protect plastic and the tray itself. I removed the 2 pieces of broken belt and figured which size it might be. Then I went to my collection of broken desktop cd drives and removed a belt. First try went ok. I installed the belt and worked flawlessly. I put cd reader part back together, tested the cd tray, it ejects and goes in fine. Then assembled back together. Then I noticed some other problem. The analog RCA was a bit lose and there was a cracked joint.... I had to unscrew the 9 screws, then the SINGLE screw that holds the 2 analog left and right in place (the single screw instead of being in the middle, it was on the left side of the left audio input). I had to detach the cables again and see what's going on on that area of the RCA input. Broken connection caused by fatigue of RCA cable input. I reflowed that connection and before that, I superglued the input to the pcb for extra strength. A bit of nail polish where the single screw sits and screwed it gently. This will prevent it from unscrewing. Assempled the cd-player again. All fine. Shame the display is a bit dim.
Oh yeah, the sellers are just insane in OLX and mercadolivre. It just infuriates me. And most good stuff, never came here to brazil. Btw, are you a fellow brazilian?
I've got a Panasonic SA-AK91. Got 'lucky' as the seller said that the tapedrive needed only a cleaning, and the cd changer needed a new belt. It was for an 'ok' price. Just had to get one computer dvd drive belt, to put in the cd changer, and it worked perfectly. But, when opening the tape drive, it was terribly corroded, my guess it wont ever work. Its sad, that i was deceived, but at least for now i dont have any tapes, nor plan on getting any, so i'm "ok" with that not working.
I just bought a refurbished Pioneer PD 88x cd player from a Hi-Fi shop. I think I overpaid in hindsight. I'll share the results when it's delivered. I hope it doesn't sound terrible. "Experts" say that newer CD players have far better digital to analog conversion.
Looks like a Sony transport, and the Sony chips on the PCB are used to control it. The DAC is a good old multibit DAC, very decent quality if nothing special. This DAC is a voltage source (as opposed to many DACs that are current sources) and does not require I/V conversion, the output stage looks like it does not have any opamps in it. In general, this simple old CD player probably sounds better than many later designs...
no surprise there Sony cdp101 was the first commercial CD player on the market. many pioneers (even their old 78 receivers ) used Sony chips ..let alone their CD players.
I would like to think that when this CD player turns to dust, an eerie wind will blow it away revealing a swastika lapel pin for no reason in particular.
Nice to see your posting videos again, been quite a bit since you've done any pc stuff!
I need to move my computer stuff to where I live now. And, equally importantly, figure out shelving so the space is used wisely.

Please do VANTAGE PC VIDEOS AGAIN ... WHERE IS YOUR PC AT AND PENTIUM PRO BUILD?
I have some potential PC stuff coming. Stay tuned. My manager has some old machines that I may be able to get.

Thanks for the breakdown!

It's so wild to me that CDs have been around for that long.
CDs were available for consumers since 1982 :)
This technology is aging rapidly, like the man who chose poorly in Indiana Jones and the Last Crusade.
I would like to think that when this CD player turns to dust, an eerie wind will blow it away revealing a swastika lapel pin for no reason in particular.
I use cassettes daily and I just wish I had more cassettes. It's an everyday hunt haha
Does this have to be hooked to a receiver to work??
Well yeah .. an amp with RCA input at least. Otherwise you'll get no sound out of the CD player.
