Ok I have 2 or 3, and 1 I cut apart before and have it sitting here with 2 intact primary winding's in it. I was going to make a 1:1 isolation transformer, but never had it welded back together, then bought an IT.
I have lots of stranded PVC insulated 18AWG. Thats on the thick side. Lots of 24, 26, +30AWG, in my house. What would be a useful transformer I could make from that for hobby use, or homemade lab test equipent ?
1 thing I could try and make is the transformer for a vacuum tube oscilloscope I own whose T. is toast. It had a split +/-325VAC, and up to +550VAC. I have the old winding somewhere, I could find it's rough turns count and wire gauge
I have the core for that too, but it's in 100 pieces and bent up a bit (dummy)
http://rhetoricity.com/misc/tubes/oscope/RCA-Oscilliscope-WO33A.pdfThat can't use much power, ot's only 4 tubes. So with the wire on hand I might try and back of the envelope what I could do with the 18ga for the primary.
There's not much room for PVC insulation. So someone once told me that I could add about 30% more turns to the primary to make it act nicer. If I can make that work, with added 18AWG, then fine. The original scope trans. winding's take little space compared to the MOT primary.
