Good catch! I only have access to the 3rd edition. Does somebody have 
the 4th edition to say whether it's been fixed? Looking up the figure 
using Mike's link only shows the bottom few characters of the figure for me.

Maybe they figure gravity will obviate the need for a compressible 
string if you hold the book upright.  :-)

Also, the bias springs in the 3rd edition are drawn like the type that 
would resist tension but obviously need to be resisting compression.  
And what is the little black knob on the end of the NPN's base door 
supposed to be?

What's to keep the CE junction "trap door" for the PNP being so far up 
that the connection to the base door is via rigid rod (hinged on both 
ends)? If I redraw it this way the notion of emitter current being 
shared by both base and collector is preserved, so I wonder what led 
them to even use a pulley (without thinking it through)?

I can't bring myself to rip off this drawing, but making improved 
versions seems very OK at the moment.
