Does anyone know if there is any way to mod the VCA on the A-107 to
reduce the noise level Right now, the output contributes quite a bit
of hiss to the signal, especially noticeable when working with
low-passed signals that don't mask the added hiss. And there doesn't
appear to be a way to bypass the VCA signal path. Ideally, I'd want
it to be at least as clean as the A-132-3 or close to it.

Kindest regards,
John
