Slightly off topic, the real VACTROL configurations are not the only ones that are useful: I have been using home-made "vactrols" rough envelope following that have 2 antiparallel LEDs with a single LED happily. It is not the configuration of a real vactrol, but it eliminates the need for a full wave rectifier.
