R-4B question





 





I'm a Drake newbie but thinking about getting an R-4B to relive my
childhood.  When was V11, the OB2 voltage regulator, introduced =
(or
removed)?  I think the R-4A has it but the R-4C doesn't.  If =
it was
removed
as the series progressed, why?

Also why is there no V6 in the schematic?
