Straightforward build: one op-amp, four transistors and some example modules f80e4975fb checkpoint before trying to add glide db7d02719b Find and replace last few thin traces, fix teardrops and gnd fill f63cfba954 Embiggen traces, add teardrops updated C5 footprint & tracing; schematic annotation updated C5 footprint & tracing; schematic annotation updates the potentiometer pads and trace routing to de-bodge the pots.

Useful here for pitching up from a base. 11 SPDT switches (many used as a full bridge rectifier; could use.
