Why?

Why should someone who elects to take a different approach from what you
advocate *deserve* problems?


**A good audio transformer is constructed using 'interleaving'. That
is: A portion of primary is overlaid with a portion of secondary,
then more primary, then more secondary and so on. Interleaves upwards
of 13 are not uncommon in high grade audio transformers. Such a
process is extremely time consuming and difficult to get right. Power
transformers (which many low end valve amp manufacturers use as
output transformers) are much cheaper to produce. One winding is
typically bunged on top of the other. End of story. They also perform
poorly.

Good audio transformers also use high grade, 'grain oriented' silicon
steel. This costs more money than the non grain-oriented stuff.

Thanks.
