Hi Yves:
I´m building the VCA, and I bought the components according to the partlist.
When I started soldering I discovered that R7 is 680 ohms in both part layouts,
but is 1K in both the part list and in the schematic.
Which one I have to use?
Thank you.

Well it depends on the input levels you are using. 680 ohm is fine for 10Vpp at the input, 1K is fine for 5Vpp at the input.
Personally I used 680 ohms.

I´m going to build mostly your modules to begin, and they are 10Vpp,
so I go for the 680 ohms then.
Thank you.
