Default OPT Quality Factors?

Is there any "quality factor" data for the Hammond 1650 series of output transformers?

Commercial secrets. Not every manufacturer is willing to spew out detail for the competition to brouse over.
I learnt the hard way, some 35 years ago purchased a quality o/p tranny and the performance was a let-down. I was tirelessly looking for a fault in the circuit when the transfomer itself was the culprit.
I do try and keep tabs on who's in the design sections.
