Hi all

=
 I like Johan went to my favourite online resources but not= hing. I looked in http://www.tubebooks.org/technical_books_online.htm where a= n old STC catalogue lists every number either side of the "4B" range .... v= ery frustrating!

If anyone has out of copyright ra= dio or audio books, manuals and catalogues there can be no better= place to send them too than Pete Millett, details on the website.(an= incredible labour of love).
