You may want to ask McIntosh or a big McIntosh dealer like Audio Classics about the function of their autoformers.
Autoformer vs Speaker impedance Curve
Autoformers vs speakers with wild impedance curve swings (for instance; MC601 amp paired with B&W 802D3 speakers).
There’s a wealth of information about tube amp audio transformers interaction with speaker impedance, but I can’t find anything regarding Autoformer and speaker impedance/phase curve relationships.
Can any techies enlighten me?
Thanks!
(I tacked a similar post onto the end of a 10 year old thread but thought I might get a few more hits with a new thread. Sorry for the redundancy)
