Hi, I'm writing to you from Italy. I own the Sansui CD-A717DR I have to replace the optics but I can't find the service manual for the calibrations the CD-a917xr is the same, would you have the pdf? great job on the straps regards Arduino
The Player is a good one but for perfect sound it needs 6 HQ OPA2604 amps instead of the cheap NE5532 industrial OP amps and all the cheap exhaust 1200 and 2700Pf Mylar (MKT) capacitors changed to styroflex or MKP caps!

Thank you for watching the video. If you change the op amp to OPA2604, it will sound very good. I also like the OPA2604, so I would definitely like to replace it.

Do u have the pickup optical for this one ? Im from Vietnam.

Thank you for watching the video. I don't own the original pickups, but the CDX-700 and CDX-900 are equipped with the same type of pickups, so please get those models first. It might be a good idea to remove the pickup from that player and use it in your player.
@@SHIN-hw4zx Agree. Even reputable brand like Wadia CD transport also adopt the VRDS mechanism. I've compared the eye-pattern signal of an ordinary transport system with a VRDS system. The VRDS produces a more stable and precise pattern

Thank you for watching my video. You can't buy this printed circuit board, but you can buy the switch attached to this printed circuit board. If it's a shop that sells electronic parts, I think they sell it. Please contact your local electronic component store. Thank you.

基盤じゃなくて基板が正しいのかな?

at the end of the video, yes it plays the CD but with a lot of operating noise, it should be almost silent, think I know why, to me the front plate of the CD drawer seems crooked. 🤔🤔
@suimeikanaudio Жыл бұрын
Thank you for watching the video. I think that the operation sound is loud because the cover is removed. Also, since it is an old player, I think that the sliding parts have deteriorated, so mechanical noise will occur. Also, replacing the belt will increase the force of opening and closing, so there is a possibility that an impact sound will occur when closing. No matter how much you repair it, it will be difficult to expect it to be as quiet as a new one.
Potresti dirmi che lubrificante usi per le guide? Le due cinghie che misure hanno?
@suimeikanaudio Жыл бұрын
Grazie per aver guardato il video. L'olio lubrificante utilizzato per la guida è grasso ceramico. Le dimensioni della cintura sono di 50 mm e 40 mm di diametro. Lo spessore è di 1,6 mm.

Very good fix, i also have to lubricate my Sony MXD-D2 because the draw is getting stuck

Most Sony CD players of this era have this symptom. If the tray does not open and close, it is fatal, so if you repair it carefully, it will work normally again. If you have a player with the same symptoms, please try to repair it.
Hi what is the thickness of the tube? 10 mm diameter but how thick the tube needs to be?I tried to order but without thickness it is not possible to buy one.Thanks
@suimeikanaudio2 жыл бұрын
Thank you for watching the video. The outer diameter of the tube is 10 mm and the inner diameter is 6 mm, so the thickness is 2 mm. For a normal compressor tube with an outer diameter of 10 mm, I think the standard is a thickness of 2 mm and an inner diameter of 6 mm. Thank you.
