VC LFO 2 not working properly

roman_f

for some reason i just have some constant output from the lfo
you may check it on the video:

in that setup it just "opens" the gain on the amplifier when i connect it with the output of lfo

here's the foto of the board, components look fine to me, but there maybe still be a mistake
thank you in advance

Hi Roman,

The first thing I always do on something like that is check the action of the knobs. In the video I saw that you were turning the large control knob, but there was no response.

Assuming that's a typical control, check the center tap and make sure that when you turn the knob, the voltage on the center tap changes. If it does, trace that wire down to the board and make sure that it's going where it needs to.

A lot of times I just do something like that because you have to start somewhere, and if you can eliminate some part of the problem, then you can keep chopping it apart until you find something that doesn't look right.

And BTW - Your panels are BEAUTIFUL! I wish I had the ability to make something half that good.
