A few more

Peter -I might be stretching the 'non-commercial' aspects here slightly with a couple of these links, but not through any advertising ploy; some of these sites have a commercial side to them, but I felt that the large amounts of freely available stuff contained was far too useful / valuable to ignore. I understand if you feel you have to delete some though.

www.zillaspeak.com Godzilla's site. The section of relevance to us is his speaker bit, unless you share Jeff's interest in teapots and monsters. Lots of stuff here, well worth investigating. I had a hand in the BIB section with our mutual friend Greg Monfort.

www.quarter-wave.com Martin J. King's site. That should be all you need to know. A collection of seminal essays, alignment tables and projects free to all. If you have even a vague interest in speaker design, this should be your first port of call. I've spoken of the rest elsewhere.

www.t-linespeakers.org Dave Dlugos hobby site. Some fun stuff here. The Classic TL stuff by John Risch is interesting for historical interest, but don't design one via this method now -see Martin's site for the better way. Some interesting projects and more besides.

www.passdiy.com SS amplifier guru Nelson Pass DIY site. Home of the Zen single gain stage SS amps, Kleinhorn, El Pipe O and many others.

http://www.yildiz.edu.tr/~ilkorur/ some great stuff here, and an excellent horn

http://www.tcaas.btinternet.co.uk/index.htm The class a amplifier site. Full schematics of many well regarded designs, including the evergreen JLH.

Some interesting stuff here: http://www.thevintageknob.org/

That should do to be going on with!
