You can download for free, or pay ~$70.

There's a pile of stuff up a few layers:

For a classical look at op amps and applications check out:

http://www.analog.com/library/analogdialogue/archives/philbrick/computing_amplifiers.html

Note the latter is a Philbrick Research (predecessor to Analog Devices) 
document from the 50's, very interesting if you like the history/origins 
of modern electronics.  To bring it back to synth - Alan R. Pearlman 
worked at Philbrick/Nexus at one point before starting ARP.  There's 
also a list of Philbrick alumuni, some the guru's of analog - you might 
recognize names like Bob Pease, and Jim Williams. Also, all sorts of 
Philbrick documents: http://www.philbrickarchive.org/
