Hi asking for any technical help here. So I was doing some general maintenance and decided to calibrate the Oscillators on my Rogue. I guess I had been using them in sync mode so I hadn't realized how totally out of range my Osc 2 was. In following the service manual I can't get in near calibration before I run out of turning space on the trim pots, but in sync mode the keyboard sounds fine. Osc 1 was calibrated without any issues whatsoever. Anyone got any pointers on what I should be looking at or for that might have gone bad? Any help is greatly appreciated.
Thanks
Barry

Re: Moog Rogue Osc 2 calibration problems
According to the service manual there is one expo for both oscillators (U7 CA3046 transistor array), so I assume the problem resides in the saw core of Osc. 2 (Q6 PNP 2n3906, U9A Half LM393). I would replace both and check again.

Re: Moog Rogue Osc 2 calibration problems
It was totally the 2n3906, however, somehow I never realized that this Moog hadn't had the gross foam goop removed, so I went down that rabbit hole. Ugh so gross. Thanks you soooooo much for the help!
