OT MkII jumpy encoder fix

nyppy · 2022-12-21T19:25:55.270Z

The encoders in my OT MkII have been acting weird and it got to the point where values would suddenly jump around without me even touching them, which would not be a lot of fun while on a MIDI page in a live setting. I couldn’t find any info online about replacement parts. Well, I’ve never been one to shy away from voiding a warranty… Access was very easy, just a couple of screws. These seem to be Alpha RV112FF-40B1-15F-0B20K-0068 encoders. They cannot be opened without desoldering, which would usually be destructive.

They’re pricey too, so before swapping all of them for new ones, I thought, what the hell, I wanted to rip them out anyway. So I gave it a go with contact cleaner through the tiny slots at the top of the encoders. So far they’re acting like new, knock on wood.

Just putting this out here in case anyone needs to google it in the future. Good luck on your repairs!

Elektron can sell you replacements if needs be, at least.

Sure, but I guess now that I figured out the part number it will be cheaper to order them from Mouser or some such place.

Hey there all. Just a heads up on the pot/encoder (differing terminology use all over, including ALPHA’s site).

The actual Digitakt encoder is the RV142FPF-40B1-15F-0B20K-004, not the RV112FF.

The key difference between the two is the former has 2 pins on top, whereas the one @nyppy mentioned (RV112FF) do not. Those only feature 4 pins on the bottom and 1 on each side.

I’ve been doing my head in looking for them as the shaft on one of my encoders completely broke off. Thanks to you @nyppy, I’ve since been able to identify the exact one!

Hope this helps!

Cheers,

Kris

Awesome, thanks for the detective work and clarification.

Good luck with the repair!

My digitone has a knob that does this from time to time. I sent it to Elektron to fix and they definitely replaced it (it sits differently and is a slightly different color, the actual encoder, not the knob) and it still does it.
I’ve grown to accept it and think of it as my little ghost producer buddy.
Sometimes he’s really on to something…
