Besides the heat build up, keep in mind that they are noisy beasts and
you really do not want one sitting next to you in a quiet working area.
What maybe a little bit more efficient is a automatic-variable
transformer in your amp range. Those are also great as line spike
absorbers, etc.. and not as noisy, unless one set the auto-adjust to
sharply.
