VCO signal goes through bus board to VCA

Hi everyone!
I need your help

I started create my own modular synth, and builded VCO and some days ago finished my VCA. But when I plugged them to bus board, I noticed, that VCO signal goes through bus board to VCA.
I think this is not problem of bus board, I think that some troubles with VCO, but don’t understand which once.
Have you got any ideas?

Is this a stripboard project? Sounds like a problem with wiring/traces?

I can’t see a way from your schems how vco output would get into the bus without some kind of error between the power header and the vco

Yeah, a stripboard project.

Blockquote Sounds like a problem with wiring/traces?

I think so, but I two days looking at stripboard and analyzing, and don’t understand where is a problem…
