Well, this circuit is not my own. It was posted on an aviation website and I copied it. The person that posted it had used it often. Others had used it. I just made one and it seemed to work for me. I have used it often too. Since posting this the negative side of it has emerged. So I am using it with caution based on the info here and on the other thread.
I did add a fuse today. First I used 1/2 amp fast acting fuse. It blew as I plugged it in. I then put in 1.5 amp and that worked. I use this in a well ventilated area and now outside the shop.
I will probably just retire it after reading here and on the other side. Maybe not a good idea after all.
