Transformer 101? was Re: New Pix UP!

Ray,

I've understood this to be true of toroid construction. Is it also
true for I-E types?

Could you elaborate on what means "built right" with respect to the
types of power transformers this list would typically use?

What should we look for when deciding between two or more (surplus)
power transformers, assuming volts and amps meet our needs...?

Thank you in advance.
