Hi there

I have Doepfer A-110-1 Standard VCO

I power it with the Doepfer DIY-Kit 1200mA

I cannot get the A-110 to work correctly :it constantly jumps from one frequency to another. (even unplugged with no entries connected)

you can listen to the example here unplugged

At first I thought I needed to warm it a little bit but even after a few hours it keeps doing the same.

I also suspected the CV bus so I removed the jumper but nothing helps

I have the impression that the module never worked & s o far it is totally useless
