Ed wrote up ways to determine transformer parameters in his blog here: http://softsolder.com/2009/02/16/finding-transformer-pi-model-parameters/ http://softsolder.com/2009/02/18/transformer-parameter-extraction-bh-curve-plotting/ It's a nice illustration of how to work up real numbers from basic principles. Sadly, the nice transformer he's measuring (another surplus unit from Goldmine Electronics) is no longer offered. - John KG4L -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
