Re: Little Phatty Stage II - unsteady volume output

Thank you for your responses. This seems to have resolved itself after a few days and I'm not sure why. The potentiometer controlling volume seems to be the most likely culprit, though I don't know enough about the LP design to know if it's even possible: one knob controls both the headphones and th...

Little Phatty Stage II - unsteady volume output

I have an LP II (circa 2010) that sounds fine through headphones, but any time I send audio to an amplifier the output volume dips and surges unpredictably. I do not see "dancing LEDs" and I don't notice any other symptoms. The problem persists when connected to any external speaker whethe...

Re: tuning, osc 1 pitch wandering

Thank you for the response. This is an exceptional forum! To answer your questions: 1) it drifts around one frequency but I don't know what frequency it will be until I turn it on. The C keys on the calibration preset have on different days sounded G#, Eb, a very flat F (too far from C to be correct...

tuning, osc 1 pitch wandering

I'm completely new to Moogs so I bought a used LP from a music store last week to learn more. (This LP is a few years old I think, no USB, gray/black, "Little Phatty (R) analog synthesizer".) I'm very impressed by the sound but I have noticed a tuning problem that has persisted after the c...
