[GreenKeys] Flesher Filter Boards

[William Wuttke]

If anyone has wanted to add 425 Hz or 850 Hz shifts to their TU-300 or
Heathkit HD-3030, or wants a spare active filter board for their TU-470,
TU-300, TU-170A, or Heathkit HD-3030, I have the solution. I wanted a fully
populated HD-3030, so just for fun, made a KiCAD project to duplicate the
Flesher board. The result is a nearly exact replica of the Flesher board.
If anyone wants one or two, let me know. Or, you can order a batch from
PCBWay.
