Just got an email form Chris (Glen of the ax84

)
he said that he doesnt offer the moonlight as a kit, however a whole parts list is available on the web site, and you can just order them all from
www.obsoleteelectronics.com or any good electronic parts store.
the bigger amps (ie the ax84 and the heavier gain version) run $184 approx, so It should be less than that.
you can probably get the board form
this guy
or just make it yourself, and save $5
