They were mentioned by Chas Miller in the Valve Radio And Audio Book. He seems to dislike the whole idea because he says one TV brand had to be recalled due to failure issues in the capacitor wattless droppers. Maybe it was the Thorn.
My HAM theory book is really pretty good for theory. It gives all the sums for calculating power factors and reactances.
