There are 7 capacitors required to build this kit. Yes DigiKey lists the
parts but half of the capacitors required for the kit show '0' stock and
none on backorder. This includes looking for substitutes of any voltage or
tolerance. I know back 10+ years ago I didn't have any problems finding
these parts. But not so in today's economy.
I still stand with my original conclusion; the parts need to build the ARRL
unit does not seem to be readably available at this time.

All of the specified values are available and appear to be in stock:
I don't know if W3NQN changed the values from an earlier version but take
another look. Good luck!
