Autoformer tech info is desired...

Have you looked at these?

This would be a good question to ask of McIntosh, since they seem to use a lot of these in their amps.

It's basically a multi-tapped primary without a secondary. Can be used as an impedence matching device, or also for volume control (ala Tribute, dave Slagle, etc.)

Marakanetz,

Look in the tweaks section of A'gon under "zero boxes". Contact Paul Speltz via his ad or use the member directory and type in paulspeltz. You can email him regarding his "autoformers". He is a great guy and can provide you with a wealth of info about autoformers. They are remarkable in what they can do for your system.
