So the most useful setting for the Mix bus is probably about 77% giving 2-3dB compression to glue it all together.

Hi Thomas, I had them made by Danbury Electronics some time ago, but I think they have changed their name to Primary windings as you say.

Sorry, I don't have the gear for that, but the new owner might post something if you ask him nicely!
