hello zoran,

cem3380/3381 are used in the a134, a135 and in
the old a130 and a131.

the newer a130 and a131 use the ca3080 chip,
just like the a132.

if you dislike exponential vca's (the a109 vca is
not really exponential, just partly) and if you don't
need amplitude modulation at audio speed, you
should try the a101/2 lpg as vca, which has
a more logarithmic response (because of the vactrols).

best wishes

ingo
