Waldorf Blofeld, Pulse 2 screen replacement - finished project

Hello everyone,

Thank you for posting this info, I recently had to do some work on my Pulse 2 and ended up here while searching. Since you’re talking about taking the thing apart and servicing it, I wanted to share what I came up with when I had to replace the encoders on my Pulse 2 after I accidentally knocked it off my desk and snapped off two of the knobs.

Alps/Alpine makes these with various torque ratings, and if you get the wrong one you can end up with a pot that is much more difficult to turn than the rest. I had no idea how to gauge this, so I basically just bought one of each and figured out compared to the rest which was appropriate.

I have not yet figured out what the main volume knob pot is using, its a four-post pot rather than three post encoder like all the other knobs. but it looks like its a 10k pot, also made by Alps-Alpine. If i figure it out I’ll come back and update my post.

The Main Encoder detented knob:
Alps Alpine EC12E24204A9

and the six editing encoders:
Alps Alpine EC12E2420801

i hope somebody finds that useful eventually. thanks for the info on the screen as well.
