Rare Sansui CD-A717DR CD Player, Given Up For Dead, Repaired & Resurrected!

- Hi everyone, come along this time as I completely resurrect this given-up-for-dead Sansui CD-A717DR CD player in one of my most challenging CD player repairs to date.
In this case, I performed the standard mechanism servicing, repaired the broken mech and laser sled linear motor, repaired the loader and made all the necessary electronic adjustments. To say I was happy when I got her running again is an understatement!
As always, please excuse the minimal editing, 'leave the goofs in' approach. It's the only way I can actually get videos out these days due to my ridiculous workload!

Great work
I am from Sri Lanka. I am a regular follower of excellent hi fi gear restoration videos.
Great Work, not just Part changing , it's what a common sense approach and actual problem-solving is all about vs throwing parts at something.
Much appreciated!
Happy to see another video from you Mike. Your work is very inspiring. Thanks!
Hi LA. You certainly get to work on & repair some of the most interesting, and exotic CD players I've ever seen. I love your organized workshop. Thank you for making and posting this video. (I've never seen a dual coil/magnet pickup drive like that. Very interesting). Excellent work.
I get so excited when I find vintage gear and fix it. I recently fixed a Yamaha CR-2040 receiver and Nakamichi 581 cassette deck. I'm over joyed having paid under $250 for both in excellent cosmetic shape.
Bought the X111 for just 10$! The Display is broken (repairable?),everything else works! Was surprised how good the thing sounds! Have a few to compare and the Sansui kicks em out of the park! Now I know why he’s so heavy for a CD player!
Just discovered your channel,great stuff! Sorry my bad english
That’s the beauty of CD’s : you can throw em around and they play scratches and all. ULTRA HD be damned
Awesome work as always Mike! I'll be sure to drop my Sony ES gear in to you when you have time 🙂
Very nice cd player, it was damaged I noticed some hair cuts I think the plastic will degrade. But it's very nice for a 30 year old player.
The dac is beautiful made. Transformers for dac and pcb for stearing the player. Most new cd players now a days have switching crap powersupplies.
I own a teac vrds10se now with ultra low jitter clock and a bnc real75 ohms digital output. Playing on a heavy modified dac.
It almost is as weight stereo image as vinyl brings.
Very nice repair sansui is worth it.
working on CD players actually seems like fun. I've got a nice old kenwood that needs some TLC I should look into
A very nice unit, showing that Sansui were still a serious manufacturer in the early 1990s. Here in the UK Sansui had pretty much given up at this point, hawking their name off to Richer Sounds to slap on cheap, low-end Taiwanese gear. Not bad kit per se but very much at the entry level.
Amazing repair! Well done!
Many thanks!
Great Job Learned A lot from this video ! Now I'm off to Repair some CD players
Glad I could help!
Ah those bumpstops! Think I have a similar issue on an Audiolab. Thanks!
Wow......wish i could work on things like that...👏
Amazing job 👏 👏 👏
Can we please move laser manufacturing back to Japan ?
Maybe you mentioned it and I missed it, but did you see the crack @14:24 ?
Where can I purchase the whole sansui system including these cd player as well
Bravo!
What do you use for the rubber bumper-stoppers? Care to do a short discourse on the lubricant(s) for the mechanical parts of audio electronics?
Thanks! I use different materials depending on what was in there, but in this case I used small pieces of a high density foam rubber material, cut to size. There is room for experimentation here.
Broken wire, well spotted 👍
Another great repair. Was that a Japanese 100v version?
This was a rare multi voltage unit, very hard to find apparently.
Hi, there! I really enjoyed watching this, especially since you now gave hope to my own dead Sansui @717dr. So, a million thx for that! But, I need some help in understanding a couple of things. First of all, how did you manage to disconnect the tray from the complex? I need to change both the belts (traybelt and the one that lifts the laser and the CD) and i order to replace the traybelt I do need to disconnect the tray, am I wrong? Secondly, what was the size of the O-rings / belts you used. My belts where totally "melted", so I couldn't use them in comparison. Love to hear from you about this! Thanks!
Hi, glad you enjoyed it and best of luck getting yours sorted! I generally fit belts from stock, sizing them up as needed. I can't recall the sizes I used here. I would suggest taking this to a CD expert though, as I suggest for most technical repair work. These are fiddly things and you must be so careful with the linear motor wiring and the laser. Then the electrical adjustments will be needed and this requires specialist equipment like you'll see in the video.
@@LiquidAudio I will do, but I would like to change the belts myself. If it doesn't work after this I will consider finding a CD expert (but thats hard these days...). But, can you remember how you detached the tray from the complex? If so, a tip would be highly appreciated. Thx, again!
@@SiffSaff Hello! Did you manage to detach the tray from the optical drive complex?
@@damianisidor5300 No, unfortunately not. It seems like I have to detach a lot of wires (that are soldered to the complex) in order to remove the tray, and then again get access to the wheels that need belts. I have little, to no knowledge of how to do this so I will not challenge the fate. I'm opening the tray manually at the moment, but it's quite a hassle so I've thought a lot about cutting a belt in one place, then placing it around the belts and in the next stage mending it together again with some kind of superglue. I suspect it won't last, but might be worth trying..? I managed to fix the optical drive complex with a new belt though, so the CD-player is no working excellent again. Do you have a tip for me, or were you looking for a solution to this problem yourself?
@@SiffSaff Any update, did you get it working or founf a repair tech ?
I recently found a music hall cd25.2 CD player and it does not spin the CD at all, I could see a laser being produced and the laser moves freely. Any idea on what to check or how to go about trying to repair it? Thank you for your time!
Hi Aaron, yes indeed but explaining what I would do if it were here in a quick comment response isn't really viable unfortunately. You need the service manual, schematic, a good DMM and an oscilloscope for general CD player work. The first thing is to check connections, voltages, look for obvious component failures and examine the load process to see where it fails. If electronics repairs are not your thing, my best suggestion is to take it someone who specialises in CD player repairs.
Don't believe that made it to the States because I have never seen that machine, I wish you lived in So. Calif. Sir.
Looks like a rebadged Technics player.
Yup - you noticed that logo on the front too ?
Not a rebadged Technics player, but uses their MASH DAC architecture. Many of the manufacturers shared technology around back in the day.
@@LiquidAudio Got ya now with dac chip but thats only part of the sound still have circutry/Power supply) Analog output stage
Junk tired that no one wants except those who still believe in illusions
That's great koto, thanks for your positive contribution! 🤣
I just wanted to mention that there is a high speed SSD and memory stick that accepts any format at any sound rate that can fit on them and what you can see can be put in the cigarette pack.
Once upon a time I fainted from these devices, the bedroom walls were practically invaded by appliances and they all did the same thing.
No resentment was just a personal opinion.
You might be surprised that many people appreciate the engineering and performance of this still very desirable "junk" koto. I'm glad you enjoy memory sticks so much, that's great. Thankfully there's room here for all of us and the things we enjoy...
PS: further silly comments will be deleted, I don't tolerate trolls 😉
Hello! Great millennial! Fast technology has nothing to do with music! Just because you have a fast SSD in a fast-paced PC doesn't mean you're listening to music. In order for your PC to play a very good recording, you need a high-performance sound card. But there is no dedicated PC sound card for musicians, only for players who want a lot of noise, not music. By the way! Do you know which are the most suitable music recording formats for PC systems? or do you listen to MP3s? :)))))
