"mick"
Thanks Patrick! A good read as usual. 
I'm not sure that Phil's website is still there. I couldn't find it, even
by changing the spelling etc.
** You just been "poned" - sonny boy.
I do have a few articles published on the net - all of them on this site:
http://sound.westhost.com/absw.htm
http://sound.westhost.com/articles/speaker-failure.html
http://sound.westhost.com/vi.htm
http://sound.westhost.com/project66.htm
http://sound.westhost.com/project86.htm
http://sound.westhost.com/project67.htm
FYI:
The articles are entirely my own work, despite the site owner's name
appearing in some headings.
