Yes, heard of this, but am not personally acquainted with Hector et al. Was reading Ashtweth's site recently about it: http://www.panacea-bocaf.org/rotoverter.htm My immediate problem was found to be the signal generator. Having recently made a bodge purchase of $160 on what amounts to a PC soundcard  instead of a signal generator. I sidled sideways away from replication thoughts (didn't have enough info on the Ebay advert, or online in searches, to know that the signal generator bought on Ebay was only for audio ranges). I do hope someone with more equipment will tackle this one ! It would probably be worthwhile, if someone has access to a number of microwave ovens or is on a good Freecycle list for such parts. 57 UK pounds per piece on the transformers could be dropped significantly using good quality salvaged items. Also, greater familiarity than most with build and test equipment would be called for during the replication. Electrical safety is paramount as well as being able to fully appreciate in data form the purported results obtainable.
