Williamson Resources:
I came up with this for a web site, which shall go nameless, whose
comment section would not take it: Williamson Resources: http://www.clarisonus.com/Archives/A...mplifier.p df Reprint of "The Williamson Amplifier: Articles reprinted from 'Wireless World', Second Edition, Iliffe, 3s/6d Net" http://www.clarisonus.com/Archives/Trans/Acro55.pdf Reprint of (1955?) Acro transformer catalog with commentary as described! http://www.radiomuseum.org/protect-p...m plifier.pdf Alternate copy of original reprint as above. http://www.chimeralabs.com/williamsmod.html Commentary on Williamson issues and proposed mods. Reasonably good. http://www.mif.pg.gda.pl/homepages/j...il/willimp.pdf http://www.frihu.com/content/diy/rc-...erstaerker.pdf (A clearer copy) Contemporary article, "Improving the Williamson Amplifier", Talbot M. Wright. Useful. http://www.keith-snook.info/Articles...0WW%201949.pdf Another version of the original article: readable. http://dalmura.com.au/projects/Williamson.php Australian site with extensive links list. http://www.technicalaudio.com/pdf/Go... mson_6550.pdf 1950s article. http://www.stan-white.com/a_doc_Williamson.htm Stan White was an audio pioneer whose work was published in the "Audio Anthologies" which all serious tube buffs should possess. He's a bit of a crank too: nevertheless this exposition is useful as an overview, although it contains information with which I certainly do not agree. http://www.technicalaudio.com/pdf/Go...-8072_xfmr.pdf Stancor literature on building a "Willy" with their transformers. As Jimmy Durante said, EVERYBODY "wanted to get into da act". All the transformer makers had suitable iron and literature promoting same. http://www.alinden.mynetcologne.de/mc/amplifiers.pdf "Amplifiers and Superlatives", a reply to 'American' (i.e. Sarser and Sprinkle) claims. http://greygum.net/sbench/sbench101/...sc/fb_faq7.txt Stability discussion of a modified Williamson design Let none of the above be taken as an endorsement of the Willy as a modern construction project. |

I would add that Heyboer is making a clone of the Peerless S-265-Q
which is the most common transformer used in US versions of the amplifier. |
