Hi There,

This is my o/p transformer picture. It is 9x9x9cm (exclude the external metal case).
I measure it, L=10.5H and DC Resistance = 114 ohm

Thanks for your attention !

Good point. Knowing what current the airgap is set for would be essentially helpful.
@ckwong99 What is the basic idea? Build an amplifier around these transformers, no matter what, or build a tube amplifier?
There is nothing wrong with wanting to build something with these transformers, but I feel it would be a lot easier and cheaper to ditch these guys and look for something else.
