Just found this site and it looks pretty good. I am starting to build this project. I have a good grasp of electronics and have been around it for some 50 years. I do not understand the connection to the ac side of the bridge; never seen a connection like it in 40 years I have understood schematics. Will try working it out and will post any tweaks here.

I am curious about two things, at least. I understand the isolation transformer, but why step up or down?  Could it not just be a 120 to 120 VAC? or 240 to 240 VAC?  Also, why tie the AC around the bridge rectifier to the capacitors? V31joepalooka
