Defective Little Phatty II

[keyboardology]

Good day,

I just bought a used Moog Little Phatty II, but there's something wrong with OSC2. It's always detuned to the extent of making every sound very wobbly (it's like all the sounds are heavily modulated). This affects most of the sounds except the ones with 'OSC Sync' on or those without OSC2 active.
Also I leave it to warm up for at least 45 minutes before I play.
The solution is to manually adjust the OSC2 frequency till it sounds right.
I did all the calibrations, and surprisingly the problem was solved. All the sounds were good with no wobble. But the very next day the problem was there again.
I was wondering if you know what the problem is and if there's a way to solve it. Your help is much appreciated.

K.

In the manual, you'll find a procedure for calibrating the oscillators and other components. Maybe worth a try.

.. or two. I've never had it but read that sometimes, running the procedure only once did not make it right. Suprising but well, worth a try.
