Hi,

You can check some Oakley Sound Systems designs as well  there are pure transistor based and some which use double 13700 to reach better performance
Tony should knows the best, you can ask him directly might not reading the list so frequently...

Br,

What would be the best VCA core design already available on the net ?
I need log/lin choice feature on control voltages.
Temperature stable, low noise, high headroom..
LM13600, LM13700, CA3080..??
The summing control voltages part is no problem.
The important part is the VCA core itself.
The best design I found so far seems to be this one:
http://hem.bredband.net/bersyn/VCA/lm13600%20vca%202.htm
but I don't know if it's LIN or LOG and
I'd rather have both possibility on the same board.

Any suggestions ?
Thanks
J-Pierre
