25" Amplifone/Wellsgardner Vector Monitor Yoke winding and information
I am now going to log my adventure in yoke winding part 2.
I am starting with my standard Amplifone setup and test my PAT9000 setup that went into storage not 100%. Not fully working. I have neck boards for 8 pin tubes but the first tube will be a 25" match and will test with a wound yoke from the past and compare that to a WG6100 yoke that I got off another member on the site here.
I first started testing things with my standard setup and got the 13" tube up so I could test my StarWars Board set and get the ESB kit working properly. I also have external test systems I think it's a WICO copy. The WICO copy is outputting signals that are a little funny as to the centering and size.
The standard setup tested the 13" tube and I got an image I was happy with.
I then plugged it into the 25" tube with the wrapped yoke and I fooled around for a bit but when I changed the yoke to the WG6100 yoke the 7924 blew almost immediately. I then dug out the PAT9000 setup that I got from Darrin and fully expected problems with it as well. Dug out the 12 Pin neckbeard and Vola it was working right out of the box. I am amazed, not surprising it came from AmazingArcading. No pun intended. So now I am testing 25" tube with the PAT9000 and getting results I can work with. I unwound the yoke #1 and think I had the wire but need to rethink the winding thing. The original Yoke are 0.5 ohms and 1.5 ohms so the WG6100 reads very low. Not surprising as my Cinamatronics reads something close like 0.5 and 1.25. My first try was one row straight across. I think that I need the same number of winds but two rows to mimic the 6100 yoke. Pictures will follow.
