Output Transformer Primary Impedance Affect on Tone

[makinrose]

Thanks for the reply! It's helpful. I have some idea about how different sectionalization schemes and grades of laminations affect the sound from a book on transformer design I read. Most manufacturers don't publish info about either the lamination types used or how a transformer is sectionalized which goes to your point about the Hammond 1650 series. My guess would be that various "clone" transformers are even less consistent.

There are a lot of factors involved so I can see your point about how unpredictable it may be.
