I understand SMPS' are difficult when you have done tube audio. It
was always the hardest thing for me to fix. Some have a wicked high
parts count & near imposable to understand. Add to that Sony is
the only one doing it this way & every one I fixed was an obvious
fix.

So even with the tranny out it won't test like a regular transformer ? So if I sent say a 30k 10 volt signal to it then it would work ? How does the transformer know what frequencies it is supposed to see ? Do appreciate the help Zeno and just trying to grasp this concept. ha !
