This is one fo the best things I have seen come along in a long time.
I am also following. Great

Thanks, it looks good but the fatal flaw is that now that the input side needs less current, the voltage on the smoothing capacitors rises and they are running close to their rated voltage. Don't know how great that is for 30 year old electrolytics. So the lifetime I might gain by running cooler I'll lose by running those capacitors too close to their rated voltage.

 :-\
New electrolytics wouldn't be such a problem, the old ones, I wouldn't be comfortable running them close to their rated voltage unless they had been run there all the time.

Those are very cool; if you should decide to sell them please let us know.
