Walter,
I didn't say it is a "regular" output transformer. I measured it with a tube and it is an SE transformer for a line output. The voltage output was 2V but it dos't matter if it was 10x less or 10x more, the results would be about the same.
For SE you need a bias current and for frequency measuments the standard* measurement methodes i use are very accurate. There is no need for an alternative methode as you discribe specially if it is a SE transformer wich you can't measure correctly that way (didn't see a bias current)
* tube + transformer or ccs + Resistor +transformer.
