I’ve been going through all my shelves in the basement and trying to complete as many of the unfinished projects as I can, just to clear some space.

One of the things I needed to do was box up the old Staco Autotransformer I have. I was faced with this:

But luckily I found Tim Reese’s webpage that explains how to hook the variac up for both 120/140v output.

So that’s one more project finished.

Green for 120v and red for 140v

Yay!
