Answers:

1) As far as the transistors, any EBC (L to R) formatted NPN will do.
They're being used as switches in this application.

2) RA was for a Cynthia-level gate out circuit which was later abandoned.
Omit these - leave all RA positions blank.

3) Detail B was the Cynthia- level gate out configuration mentioned above.

4) The BOM is indeed missing those - sorry about that. They need to be
there as they provide short circuit protection so you can, in effect mult
the gate outs together.

hope this helps,
