Model 15 Oscillator warble

Hi

One of the 921b’s on my model 15 has suddenly started doing random pitches or warbling when I move the octave switch.

The 921b next to it is fine.

Any ideas what might be causing that ?

Thanks.

Sorry you are having so much trouble with your 15. I had 2 thoughts. The switch itself may be failing. a squirt of Deoxit may help. Make sure the edge connector on the back of the module is fully seated.

Yeah it’s definitely the octave switch because basic things like blowing on it helped a bit - put even different finger pressure on the switch can bend the pitch. I’ll try this spray first and then I guess it’s off to the tech.
