Hello all.

I’ve just noticed an unusual behaviour on my A132-3 Dual VCA

With no gain and 0 cv the bottom channel is letting bleed through.

It seems to be on linear mode only, and it is easily audible. Top channel is fine.

Looking at the pcb my module is a v2 revision with two TL074CN IC’s and  and one V2146D IC.

If anyone can advise it would be really helpful as I need to use the module to gate two channels of samples at a theatre event soon. The sample material suits a linear response, so I really need both channels to open and close at a similar rate, and to close to silence!

Many thanks,

Neal

BTW  It’s a small LC1 rack, though I’ve tried it in my LC 3 and LC 6. I’m also using a recently purchased Doepfer A140-2 which I completely love. It pairs with the A132-3 really well and is so compact and useful, especially for stereo signals and twin voices. Would recommend it to anyone wanting to save HP.
