Output Transformer impedance matching & testing site.

[Yorkie]

Very interesting and useful article that de-mystifies how to determine output transformer impedances and how, with simple gear, we can check the impedance of an unknown output transformer.

(Given that impedance is not the same thing as resistance or inductance):

Hope that's of interest.

Thanks for posting that link David. I think we all have output transformers saved that we've pulled from various scrap chassis. Very useful to be able to check them out for use in a particular circuit.
