2016 re-issue Osc 1 problem

[trontastic]

I have a 2016 model d re-issure. Was working great. Now OSC 1 just stopped working on lower keys when set to lower range, and on the upper keys/high ranges it sounds "sickly", kind of wavering in tune and distorted. But OSC 2 & 3 sound normal. Anyone else have this problem?

Could it be a dirty range switch.

I have done a forum search , but not many popped up , and ones that did have had no resolves.

Any pointers will help.
Thanks.

Hi,

replace C1 (10nF mica or polystyrene flex)

Have fun!

Thank you.
Sorry only just picked this up.
Hope it works for me.

Okay so far so good. Replacing C1 on Osc pcb has worked ( 22 May 2024 ).

Thanks for the tip by RL.
Cheers and lets hope this work for a long time.

OK i know its only been 2 days since i changed C1, but the mini Ocs 1 is still in tune from switch on.
I'm well pleased because i have no Tech guy to fix it around here. I have a small amount of electronic
knowledge but was able to do this easy fix.
Hope by putting this up here others will benefit.

It would help if I had known this in 2017
I had exactly this problem and unfortunately had to send the entire device in for warranty service at the time, but good to know. Thanks anyway.

dann war dein Mini schon einmal auf meinem Platz - ist doch gut

[Herr Mosa]

Oh schau an - dann bedanke ich mich nachträglich gerne noch direkt!
Das Teil erneut auf die Paketreise zu schicken war schon aufregend - aber ging ja gut
