I was luckier. My EE class (Univ of Cincinnati, 1964) was the last that was 
required purchase the complete 5-volume set of RCA tube manuals. We used 
them extensively (to study load lines), but we also studied solid state 
electronics. We had two text books for circuit analysis -- one an excellent older 
one by Bill Middendorf, who taught the course (he was also a great teacher), 
and the other a newer one that was better suited to analysis of solid state 
electronics.  

All of this stuff is still in my library, along with Terman, Radiotron Designer's 
Handbook, etc.
