Original poster: "Jack King" <ekklekktikk@xxxxxxxxxxx> Greetings Shelton,Over the years messin with TCs and my extensive dabbling in all things neon, I have found an old acme or sola 7.5 kva slide choke to be best suited to your application (they are identical in performance and somebody copied somebody else type thing) - THis was using a 14,400 - 120-1 1.5 kva PT trans with a nom 120 v input. I cant recall the inductance range, but with said PT it produced about 50 ma start current and up in the 650 - 700 ma range with the core all but out (there was still headroom but I didnt wanna push it) - load was a cold cathode tube.
If you wanna save yourself a lot of headache and have something that is proven to work superb with these PTs this is the answer. I have a few fully assembled iron cores from these chokes and one "tunnel" (wire form) - these were originally wound with #10 mag wire (like haptz) and 3 layers. The iron slug is appx 17" long with a cross section of about 2". I may have a complete working unit around the shop too.
Email me if I can be of help - or call 801-604-5136 (10 am - 10 pm MST) Jack King

J." <hsheltonj@xxxxxxxxx> Hi Everyone, Ive just aquired as of Saturday, May 05 2007, A nice PT from Aaron H..Although, I need to make a ballast for it so I can finally turn the thing on :D I would like to mkae one that is about capapable of being variable between 1A and 40A or so and, i would like some help on constructing one. I have poked around on the internet and on the list but, most links that were given are now dead or, the topic was so old, the technology is like out of date. I need help because, I have NO idea how large this thing should be and how to start going about making it, what gauge wire to wrap around the PVC, how many turns, how long should the PVC Be, etc...I can go and buy stuff but, as of now, I have PVC pipe in the ranges of 1.5" ID to 6" ID, loads of coax cable, 2 100 ft. rolls of 18g baling wire, 10' .25" copper refrigerator tubing, 22AWG magnet wire, and..some other stuff.So, any ideas from people that have made this kind of variable ballast, throw them out there for all to learn.Thank You, Shelton Thank You, H.S.J.
