NST to HVPS

Here's another interesting video from my favorite cross-dresser.

As noted regarding my images posted at my trading post store, I have depotted many neon transformers in the 90's and am geting rid of a bunch of them. It is a super messy job and never worth the effort, in the end.

Richard, thanks for your thoughtful assessment of the video. I was under the the delusional impression that someone who has limited resources and little or no access to a professional HVPS would benefit from the fairly thorough demonstration of how to build one from scratch with an NST.

I'll openly admit that I had totally overlooked the reality of the fact that this approach to the project might cause the uninitiated newb to inadvertently get his/her hands dirty. Things were different in my day. I'm a throwback to the times when we did whatever was necessary to get to our goal. It's unfortunate that your own efforts in the past didn't pay off.

I guess I don't understand how my efforts didn't pay off. The efforts were all 100% successful and, ultimately, useful. Those depotteds ran Tesla coils. They are still good. I did what I had to do to reach my goal. Unfortunately at even $10.00 per hour and about 5 hours labor and nearly a gallon of cleaner you could have found a potted used item for much less and zero effort. That was in the 90's

Today, the old iron core units are tough to get and I am sure the new ones are over $200.00 from those manufacturers still making them.

My comments are to try and avoid depotting at all costs. For most folks, it will not end well for any number of reasons. If a transfomrer is defective and free, depotting and a lot of effort may be able to fix it. If working, never, ever depot, as it is a fools errand.
