Have a look here for some circuits:

http://www.musicfromouterspace.com/analogsynth/AAA_OscillatorIndex.php?page=ANALOG
http://www.uni-bonn.de/~uzs159/

If you can find a copy, try to get a hold of the book "Musical
Applications of Microprocessors" by Hal Chamberlin - copies show up on
Ebay from time to time. Though it's a couple decades old, the book has
lots of analog synth circuits, and most importantly good explanations of
exactly how the circuits work.

There was an excellent series called "Electronotes" published by a
physicist named Bernie Hutchings back in the 1980's that you might be
able to dig up somewhere. It was a treasure trove of synthesizer
theory and practical circuit examples of VCOs, VCFs, VCAs, ADSR EGs
etc.

Well. It turns out he's still in business here: http://electronotes.netfirms.com/
and I misspelled his name. It's Bernie Hutchins and he's a recently
retired EE prof from Cornell. Some of his stuff is pretty old, but
analog synthesis hasn't really changed that much.
