[TCML] Subject: Overheated Secondary

[bartb]

Hi Marko,

I suspect a secondary short (and then the overheating occurred). This 
would be the norm.

Just unwind a few layers (about 100V loss per layer I expect). Also, 
don't pot until you measure output. The windings have to be put on in 
the correct winding polarity (which if you didn't mark their direction 
before you took it apart you may have to do a quick trial and error test 
to get it right).

Take care,
Bart
