Good to hear things worked out OK. However.......testing at the low voltages you describe verify the ratios under unrealistic conditions. If they were mine, I'd perform one more test: wire in a 1amp fuse in series with the primary, make sure all secondary leads are separated and not in contact with anything and plug into 120VAC. The test here is that the fuse doesn't blow immediately or after a minute or two. If it passes this test too then you know internal insulation is good at operating voltages. Good luck with your project.

Hi Steve, thanks. Besides the 800 plus volts measurements I turned up my variovac to 120 volts on the lower voltages and both transformers were mirror perfect in measures they needed to achieve. Would that be ok? Thanks Mark...Thanks you others for the pep talks...love em!...Mark.
