AJH Synth VCO - Pitch instability

Hi,

Bought an AJH Synth VCO here in MG and when it arrived i noticed a strange behavior. The VCO was completely unstable in terms of pitch.
I've started to make some test plugging it into different cases (doepfer psu3 and erica synth). Nothing changed. I've tried to send CV from different sources (3 or 4 sequencers), same story.

I've come across this last night, it's exactly my case: https://modwiggler.com/forum/viewtopic.php?t=220598

Anyone had the same issue?

I think this module is defected.

Thanks

Hmmm... that's a shame. I've had nothing but good luck with AJH modules.
Looks like you may have found your answer in that MW thread. Reach out to AJH and see if they can offer you some guidance.
Good luck.
