Hello All
I recently built the CV output circuit with the intention of using it with my Moog Rogue. Once completed, I connected the circuit to the CV ring input on my synthesizer. Much to my excitement, the hotrod worked out as intended… for a few hours. Unfortunately, the circuit later became less sensitive to capacitance on the volume antenna. So, I performed some tests and found that the voltage at pin 9 of U3 (also at the output jack of the CV circuit) was not fluctuating between +10V and zero, but holding steady, rather, at +8V -regardless of activity near the volume antenna. It’s funny, cause the volume circuit operates as it should through the main audio output.
Could this be a tuning issue? Might there be a problem with U3?
I rebuilt the CV output circuit and am getting the same +10V at pin 9…
Hmmmm,
