The box is only technically grounded properly if you use one of the outlets with the metal tab that holds the screw to transfer the ground through if things are loose. The ones that have the one screw loose and the other one semi captive. might be worth putting a ground jumper between the box and the ground wire. Otherwise great design and even polarizes the lights like it properly.
How about showing folks how to build a bucking transformer to lower the line voltage entering vintage tube gear? Plenty of dim-bulb videos out there… I would make one myself but I’m butt-ugly 😂!
I hope you consider changing the name of this wonderful video, so a novice like me can find it more easily. This is the best video about building a dim bulb tester. Thanks!
Not picking on you but I did a search on YT for a dim bulb tester and stopped counting after 100 videos showing how to build a dim bulb tester. As an engineer for the last 45 years, I have to say this is nothing new or novel. TV techs started making these back in at least the 1950's an probably earlier. It is not a bad thing to build or have but it only tells one that something is drawing way too much current. A variac and simple amp meter, clamp on or in series is what most of us have used for decades. I guess I am surprised at the excitement over this very basic design. When you flip a switch on any table lamp to on, you have in essence, created a dim bulb tester, less an opening in the circuit for plugging an outlet to supply some device which runs off of AC. And that is the down side to a DBT is it only tells one something is drawing excessive current and nothing more. I suppose, I find this kind of amusing in some way. Good luck !!
Whoaaaa, what a cool way to build one, cant wait to make my own… thx :-)
Thank you. Great video as I followed your process to build one on my own.

This was a video I did the voiceover work on. You should subscribe to the TubeDepot UA-cam channel for more videos like this! 😁

Man I just did the voice over on this lol but I appreciate you watching the video!
