Using terminal boards is of course somewhat more expensive than not using 
them.  Bit it is far easier to locate a component on a terminal board than 
one in a set were the wiring and components run everywhere helter-skelter.  I 
skipped A-School and B-School but I would imagine that it is much easier to 
teach a set to a bunch of green techs if all of most or the components are 
laid out neatly than in the typical 1950's/60's rat's nest.

As far as tubes are concerned, the only advantage that a 6SK7 has over a 
6K7 is that it's cheaper to make and marginally cheaper to wire up.  A set 
with 6K7's in it is likely to be quicker to trouble-shoot than one with 6SK7's.
