hey-Hey!!!, There is a single addition, a MC stage. I am not sure I like the idea of step-up transformers. Probably do a nice FET-input OP amp configured for ~20:1 gain. Easy access to C and R loading. Those little pF polystyrene caps are pretty sweet. The two chassis design will let me build a low voltage supply and run it through the same umbilical. Black AMP connectors will do...:) cheers, Douglas
