Refurbishing an Akai AX60 Synth
Just about everything that I do in this video I was able to do thanks to GOLT!'s excellent tutorials. Here are the links to the GOLT! videos I reference in my video:

KORG DW-6000 : The Jam
zhlédnutí 1,5KPřed 6 měsíci
Personally I think that the Korg DW-6000 is one of the most underrated synths from the mid-80s, largely due to the fact that the Korg factory presets are absolute garbage. Here is a set created by AnalogAudio1 which really bring this synth to life. Just added a small amount of hall reverb, otherwise what you hear on the video is exactly what came out of the DW-6000. Stay tuned for the repair vi...
I just bought that same oscilloscope to fix my juno 106 :) def worth it!
So good, I love the dw8000, im legit sitting next to it in the studio... Korg really should do another fullsize run of the dw8000, multi timbrality would have been really the only thing i would want added, along with sick surface controls obviously.
Subbed.
hi i got a question i hope u can help me because i really don't know how to start , everything works except for Yes Button
Sounds like you need to replace the Yes button switch. It's fairly easy to do. You will need to buy a TACT SWITCH 12*12MM 7.3MM THROUGH HOLE SPST from a place like Tayda or Mouser.
Nice work ! Pretty much what I do when rebuilding.
I watched your two videos about this repair, I also have a DW8000 and I love this instrument, your step by step was very interesting and instructive, I also do my repairs and I say that I am not a 'mega technician', I am like you, I do my trials and errors and try to find someone to blame for some defect. Congratulations on the video
too bad the digital oscillator/analog filter concept wasn't explored a little longer. it had a brief window in the mid 80s, then affordable sampling came along and that was that. this was really the last period of real synthesizers.
Sounds like we will be there for a few hours and then we can catch up ⬆️ the sounds
Great work - had one of these from a fire damage sale and it had issues different to yours but still took a while to get it there. Having a 2nd working unit to reference is invaluable. And yes the keyboard assembly/disassembly was a royal pita. But I now have two working so can stack or run them in true stereo for that huge Oberheim sound.
Loving these videos man!
Nice work! I just recently reacquired my Oberheim Matrix-6 keyboard and installed all of my old patches on there. I'm running through a Boss Super Chorus CE 300 and a Bigsky reverb unit and my OB-6 is getting a bit jealous. Thanks for this great and informative upload!
great vid. Incredible that the buttons work. I find old synths with sticky buttons so often
You should have used solder wik that sucks the solder up. That way you could have replaced the LCD's in a flash. even if they where not defective. But you also should have removed all those wires prior to that. to prevent all that damage. These displays almost never fail, it's the wiring or the drivers (IC's)
Interesting video - congratulations on the repair. I suspect that another problem that may arise with equipment of this age is the electrolytic capacitors - it is best to preemptively replace all of them so that they do not spill and cause more damage in the future....
I agree. In this case I believe both the caps and voltage regulators had been previously replaced by the last owner. But yeah, great advice!
I though you can't fix it, good job!
Great sounding synth.
Wonderful machine. I remember playing it in the shop where I got the DW 6000 - couldn't afford the 8000 so bought the baby brother. Thanks for the memories. Still have the 6000 but can't remember when I last switched it on.
I think the DW-6000 is also a great sounding synth. In some cases I've been able to get the 6000 and 8000 sound almost identical. You can check out the Jam video I did for the DW-6000 where you can hear some of the sounds, I think it's an impressive little synth!
nice
Its a fantastic sound, I knew Korg made great synths around this time but I didn't realise they were that good, I just looked it up and its hard to get, even the rack unit, hopefully I can get one sometime it would flesh out my small collection of synths :)
Check out the DW-6000 jam as well, I think it's a crazy great sounding synth too. It's too bad you probably don't live around here because I'm actually selling off one of my DW-8000's right now.
I am trying to replace the battery that is on the board you took out. But you do not show the removal.... Why? The info you give is nice but SHOW YOUR WORK.. At 8:20 your cut away is madding.
First of all I'm not a professional, I don't get paid for any of this, and no...I don't make any money whatsoever from. the ads that Google is imposing on all of us. I don't always catch everything on video unfortunately, but I also assume that certain things will be fairly simple for people to figure out. Replacing the battery is pretty simple, just unsolder the old one (carefully...don't strip or pull the traces off), then get yourself an inexpensive 2032-style battery holder for the 3.3V flat battery that you can buy just about anywhere. There is a positive that is clearly marked on the circuit board, you can see it clearly at the 28:38 mark. On those battery holders, the positive is at the top, so just colder the adapter in place of the old battery and make sure you insert the new battery in the correct direction. All in all it's pretty straightforward, but if you have other more complicated issues I'll try to help if I can. Alternatively you can also request for a video with more detailed explanation, although when I can get around to doing it depends on my schedule etc.
@@kayslabs First of all ? You making money on the video is irrelevant. I do not need help on buying a battery or diagnosing the issue and no did I ask you about the need to buy at battery where it is or what type or how much they are or even about the clip. My comment was based on the fact you did not show removal of the circuit board. [ the 3 screws on the midi i/o was the part I missed]. That was the part that I needed to see. My apologies if I have bruised your ego. Assume? What that every person that watches your video is a certified repair tech and have worked on the Matrix 6? There will be no request.
@StevenBardo you could have removed your battery in the time you have spent being circular argumentative.
@@Slipstreamaudio. " circular argumentative." ??? Thank your for your useless comment. I had already removed the board and replaced the battery. I acknowledged Keylabs help, "The info you give is nice" in my original post. Done before I replied to him. Have a nice day. Show your work.
Normally I like trolls. You’re an annoying troll.
When it comes to the slider, would using (I forget what it's called) the carbon paint be an option? I've used it before repairing drum machine pad contacts.
I really enjoy your videos. If you don’t mind sharing what was the solder remover gun model?
Thank you. I got me a Hakko FR-301. It's a bit more pricey than the other brands, but everyone swears by it and it's quite good.
I have rarely had the chance to play an Oberheim, but when you do there is something special that happens. They just sound incredible. Unlike any other synth Ive ever known!
I love your video, but the background "music" is *very* annoying. ( but not the one when you did the sped up soldering. ) Just my opinion, for what its worth.
I will turn down the music level in Part 2 so that hopefully it's less annoying.
Hi Kays. I have a DW6000 that was damaged when plugged into wrong supply so your PSU discussion was very helpful. Thanks for sharing.
Oh cool...glad you found it useful. I'm planning a future video where I discuss some of the most common failure points in these types of synths (and most of them are pretty simple stuff).
Omg 😱 . 😮 sounds so dope!!!
Nice fix.
I've got a similar situation except I have one good DW8000 and one that lights up but just does nothing more. Will probably be going down the same route.
My DW 8000 repair video is coming up next!
Sounds great!
Buy a hakko desoldering gun. You will love it
I did and I do. Have no idea how in the world I was able to function before!
Thank you! I was waiting for the sequal. Very interesting.
Dream Theater used DW-8000 in Pull me under. I obtained nonfunctuonal DW-8000. I mean to repair it some day! Great sounding Synths, Great demo!
I will have a DW8000 repair video going up after I finish up with the DW 6000 and a surprise addition. Stay tuned!
@@kayslabs Oh, I will be looking forward to it! My DW-8000 was making low volume noise (I figure I just needed to reinstall sounds at that stage) but I must have shorted something (the fuse died) and DW is not turning now. I might need a new fuse and then will need to install sounds. I don't get how preset patches of DW are installed from 'sound file'.
Wheres the patches???
Lots of keyboards from this era have unpopulated slots, components, even connector pins. Minor improvements were often made to circuit designs during the production run of an instrument - The JX-8P is a good example of this. That resistor under the CPU board of the broken unit looks factory. Also, even though you cleaned the surface of the board underneath the EPROM and SRAM chips (IC2 and 3), the traces are still quite corroded. Have you checked continuity on all of them? Regardless, that corrosion will progress and is likely to cause future problems, even IF the traces are still providing continuity today. I would remove those sockets again (sorry!) and use a scalpel to scrape back ALL the dark corroded areas under IC2 and 3 and around C35, etc. until you see only clean bare copper (a fiber glass brush is also helpful). Any broken traces should be repaired with bare wire + solder and then all of the scraped traces should be rechecked then resealed with conformal coating. Other questions: Do the PSU rails test as they should under load? Is IC1 getting power, clock and reset as it should? Are IC 2 and 3 getting power? Use an oscilloscope to probe the critical pins on IC1, 2, and 3 on your working unit and then check the bad unit. That spill could have caused a short and damaged an IC or 2 as well. Good luck!!!
Thank you for sharing. Some great insights here. enjoyed the process ✨
Great video - so real, thanks for sharing! 🙏 good luck!
What a suspens! Now we're all waiting for the part 2!
A better way to repair this kind of damage is to get AWG 30 Kynar wire and a stripper for it. Don't try to solder to very fine traces. Solder to pins of IC's, vias, and leads of components. It will be much more reliable. Also, the service manual for the M6 is available on the web and would show the connections to the EPROM. No need to figure it out from another board.
Regarding the unpopulated seats of the board, maybe the keyboard shares the board with the DW-8000 and the parts are only present in that model.
Great job, congratulations man :) I just saw pin 5 of an IC is not inside the socket.It's on the very top just right below the display At 3:26 it's clear to see, there you point at it with the screwdriver.. but seems not to harm too much :D Thanks for showing the details!
Have the same synth with similar issues although it does show display and responds to data changes. The only sound is that drop sound you had. I have also changed the same chip with new one but drop sound still persists. Thanks for showing your DIY skills. Great you got it working again
Anche il mio dw ha quel suono orrendo ma i led sono accesi, attendo con ansia la seconda parte! Voi avete risolto?
Love this, it's so satisfying to see an old synth being brought back to life :)
One of my favourite synths. A very nice sounding poly.
This was cool. Just bought a Matrix 6 with no output. Seller says it may be D/A converter. I’m new to repair so this is super helpful!
I know the eBay listing and was watching it. What did you end up picking it up for? I'm not sure if the D/A converter would necessarily be bad, but something to check. Anyway, thanks for watching...part 2 is coming up soon!
Why does every Matrix owner always play those same noisy toneless note-free patches 🥴
Great job!
hi bro i would love to work with on some , can u please give me a mail or your instagram info to text u ? thanks
bro i would love to work with u on some can u give me some contact to text u, thanks !
So Glad I snatched one of these up!! It was the synth I REALLY wanted to buy when I moved to Vermont back in 1985 but the music store only had a Juno 106 which I loved... But this really would have been a much better fit for me..... Not sorry I bought the Juno but in hindsight this would have been a much better fit for the music I was playing back then.... Nice video!!! Thanks for doing this!!!
astounding brass and string pads--lots of bizarre sfx too---totally underrated OB. so far superior to that a-bomb-inable thin, harsh OB-6. great creamy lushness.
Thank you for telling me that the OB-6 sounds thin and harsh. Neither me nor thousands of other users ever noticed that.
