DOEPFER A 132-3 V2 bleed MOD

I love all my my Doepfer A100 gear, it's what got me into modular in the first place!

Recently I noticed a bleed issue with my A132-3 Dual VCA.

It only seemed to happen in linear mode, and only with one channel.  A post to the excellent Doepfer Yahoo group yielded a reply from Herr Doepfer himself.

"Hello,

V2 is an older version from 2010. Due to tolerances of the V2164D sometimes

the VCA does not close with CV=0. To avoid this a high value resistor (e.g.

4M7) has to be added between pin 4 (upper VCA) or pin 5 (lower VCA) of the

V2164 and -12V. This adds a small negative voltage to the CV summing

node. -12V is available e.g. at pin 9 of the V2164 or the wire bridge "J1"

below the V2164.

In V3 and V4 of the module the 4M7 resistors have been added.

Hope this helps

Dieter Doepfer"

A quick mod with two hefty 4M7 Resisitors and my Dual VCA closes to silence. Stuff like this makes realise why I love the modular scene.

I don't think many units with this problem were shipped, but I'm posting this just in case it might help any other folk...

Job Done.
