Ecler Eternal magnetic fader teardown 

@5:44 Actually the square wave is filtered by the resonance of L101 (68uH) and C104 (10nF) thusly filtered into a Sine-Wave, which is then Amplified by Op-Amp IC104 and fed into the Inductor. Thank you very much for the schematic! Liked and subscribed FOR SURE!!!

Thank you! I've owned a HAK 360 on two occasions (still own one, but with an Innofader), but never looked at the insides of an Eternal. They barely needed any maintenance, ever.

I never expected that some faders are so special and excellent engineered. Great video!

Absolutely fantastic video! Your videos are outstanding! I love these deep dives into DJ tech!

pure knowledge! thanks !

Amazing video. Thanks for the teardown!

excellent video.

Can we get a link to the manual? I would love to get a closer look at that schematic

É possível fabricar em casa?

Mine stopped working, cant figure out why. Channel faders and eqs are working. Crossfader seems just bypassed 😢

Hey Andy. I just resurrected my Ecler HAK 360 that I inherited off my late friend Soren. I absolutely love the fader and mixer in general but I'm getting weird crackling, distortion and left channel dropouts and all sorts of weirdness. Was wondering if you had any ideas what was causing this? I took out the fader and gave everything a good clean but it's still happening. Cheers bruv

Woah. So a multi-layer PCB transformer?

What happens if you put or move a strong magnet near such fader?

Hi. I'm trying to find an L101 inductor 68 uH 0.13A that is located in left upper corner of pcb. Can you tell what original part is?

"Actually, that gives me an idea"

The mechanism reminds me of an LVDT.

😲wow!

isnt the metal in the carlsberg can aluminium too?

Does anyone out there find this fader repeatedly gets sticky from the glue holding the metal squares in place?? I'm CONSTANTLY having to open her up and scrub between these boards with alcohol, wiping away the yellowy sticky residue that seems to just appear. The metal slider is touching one of these boards as it moves back and forth (there is a mm or so of vertical play if you move the fader cap up and down, and it will touch the board), but that only seems to matter if there is a build up of glue, so if it gets sticky (usually after a few days of heavy use) i'll open it up and there will be glue on the slider plate too. (should i be adding red deoxit to reduce friction here or not?) Also, the glue holding the slider plate to the plastic slider has failed so now I'm periodically glueing that back on too.... I had the fader a little under a year before i started to have issues. :( I can see one comment here saying they barely ever need maintenance but that is the opposite of my experience. I'm genuinely gutted as i can't afford to replace rn and i just want to practice!!!!! Respect to @TheRasteri for the amazing video, i can't find much else out there so any comments would be greatly appreciated!!!! ✌️

I imagine a fader based on magnetism can be made an easier way. For example, using hall effect sensors at both ends.

if it was magnetic it would be attracted to the magnetic force of the transformer I would assume

Can i pay you to create a device for me?.i have a idea for a device that i want to become a reality

Aluminium does not corrode easily, cheap and easy to manufacture.
