The autoformer doesn't work like Sean thinks it does.. Mcintosh output transformers are bifilar wound which is a complex technique used to nearly eliminate the inductance associated with the wire. We use it in the lab for special EMI filters (different core setup though). The coupling is just about perfect with a larger bandwidth than the output transistors. Just like tube amps - only better because not all manufactuers have the ability to bifilar wind their trannies.
MC352 into varying-load speaker?
Subject says it all... how well does the autoformer handle a nominal 4 ohm speaker which is not flat? I can't seem to get a good understanding of this situation with my limited technical knowledge of this sort of thing.
Speakers are Usher 8871 in a large space. They are rated at 90db, 4 ohms but seem to be much hungrier. I onced owned a Mac 6500 (200 w into 4 ohms) that while sounding great did not satisfy with classical music owing to power limitations.
