Anyone have a schematic for an MB Simul-Satellite?

I'm doing some fine tuning on a Satellite head that I'm using as a kind of D-lator/ boost and want to tame or make the boost variable.

The kind folks at MB sent me the pre-amp schematic and attenuating the boost (actually un-attenuating the normal) was as easy as paralleling a 100k resistor to the 22k that's after the V1a cathode cap. I did some small mods to the tone circuit to taste and am very pleased with the results.
It's kind of acting as a D-lator with a post send tone control and clean boost.
