Build Notes

  • 2n4916 transistors are no longer being made; not unobtainium, but you'll have to look for them surplus or ebay. I tried a couple common substitutions and they did not work, but I didn't dig hard to find matches based on spec. If anyone does find a modern equivelent I'd be interested to hear.
  • I've used a few different inductors succesfully, including both the mouser compenents mentioned. Some are wider than the PCB footprint, but it's easy enough to bend the leads around a bit to fit.
