Beautiful site Kevin!
Very interesting thread on transformer breakin!
Any speculation as to what is happening here?
Windings getting looser, core going through changes, a little bit of both?
I thought I was seeing inductance changes while sweeping several transformers, but I figured it was this old Gen Rad impedance bridge drifting around.
Also, what are your thoughts on how a transformer nulls out?
I noticed that most vintage units seem to have a very touchy null if you are patient.
Some new brands seem to have kind of a mushy null.
I wonder if this relates to how they sound?
Interesting things, these transformers!
