Grant has agreed to assemble and send to me retrofit kits for my 
Envelators to make the modification specified by Christophe.  It is 
quite simple, involving a ganged pot-switch (pull on, push off) with a 
capacitor soldered on the switch.  Two wires are attached to a location 
on the board that is a presently vacant spot for a diode.

(You will have to check with Grant regarding cost).
