I've ordered and I'm waiting for the first run of prototype boards for the VW-101 power module. This is a 3.5 amp three rail linear supply with a maximum 1.5 amp on each channel (total is still 3.5 amp).

This is a pretty straightforward design using a center tap 28V transformer, 4A bridge rectifier, some bypass and smoothing caps, and three L79C series regulators.

No board layout yet. I want to do a cursory inspection when the prototypes arrive to make sure there are no major mistakes. When it's been verified I'll post gerbers and kicad files.
