An output transformer for a tube guitar amp is easy stuff compared
to a typical Jensen line or mic input transformer:

* It doesn't need to be high quality. The amp will actually
  sound better if it distorts a bit.
* It can have some nice resonances in the audio band, that
  will probably just enhance the sound.
* No need for magnetic screening.
* No need for electrostatic screening between primary and
  secondary.
* No need for careful balancing and high CMRR.
* Can be bulky and heavy.
* etc.

$200 for a mic input transformer is really high end, but that
should be compared to the price of a quality microphone, which
could easily be ten times as much.

There are three of them, and Alleline.
