I'm putting together a small group buy of NAP250 boards.
This is a true nostalgia project with considerable research done into the original circuit and device selection. I'm even deleting the silkscreen and solder-mask on the boards. (It will be a two layer board with plated-through holes and a lead-free HASL finish, so not entirely old-school).
I have designs for both the original regulators (again, without SOA), and an inverted one which references the VAS to ground, greatly increasing its PSRR at high frequency.

Please copy the last-posted list and add your own name, along with which regulators you're interested in.
Cheers,
Jeff.
