As soon as the vactrol module is available we will publish all applications.
The A/D control of the A-143-1 will be one of the examples. As I'm very busy
because of the Christmas/end-of-the-year orders and the NAMM preparations I
will not have time to prepare this information within the next next few
days. But e.g. for the A/D/R controls (e.g. A-140, A-143-1, A-143-2) it's
very simple: the vactrol has to be connected in parallel to the terminals of
the corresponding rotary potentiometer and the potentiometer has to be set
to its maximum resistance (i.e. normally fully CW). For the lowest of the
four sub-modules of the A-143-1 it is very easy to find the suitable points
on the bottom side of the pcb.
