Testing Transformers with Square Waves

While truffling about on the 'web I came across this article, which I thought might amuse some here: http://www.electra-print.com/techblog.php

Sigh.

I don't know Jack (there, I admitted it :razz: ). But...

My friend Don once ordered a power transformer from him for an elaborate tube/solid-state line-level crossover of my design. There was a moment when I think Elliano was about to refuse to make it, because when Don told him what the requested voltages and currents were, he said something was terribly wrong---that it was crazy. There was simply no way that you needed that.

From the custom power transformer page:

If a power transformer is left on continuously it will continue to heat up and could fail.

Huh? That's news to me. :roll:

I always that that a transformer that overheats is either underpowered, faulty, or there is DC on the line.

Tell that to the Power Company!

Has anyone here used his audio transformers?

This could be his version of Zeno's Paradox.

Jack makes some good SE transformers.

I think he works out of Las Vegas.

I asked him about Bartolucci inductors, which are wound on a hi perm C Core, he said M6 was best for incremental inductors, I never did understand that.

I really want to try some f thos Bartolucci chokes, but they cost a fortune.
