Dynadim light dimmer circuit

[shokjok]

I remember either Electronics Hobbyist or Electronic Experimenter's Handbook from the early 1980's featuring a light dimmer circuit named Dynadim. The circuit dims an incandescent light bulb with a preset delay using a slide potentiometer interfaced to a MOSFET ( dual-gate like a 40673?), fitting inside a common electrical wall box. If I remember correctly, a blank wallplate can be cut for this circuit to fit onto the box. My magazine collection was stolen from me in a rental dispute last year, and Googling the name gives unacceptable results. Can anyone post the circuit for me, please?
