Crowhurst paper on output xformer search

After long searching, I've found two interesting paper on Audio Output Transformer by Crowhurst. If somebody interested, these papers can be downloaded from:

http://213.156.45.208/primo/materiale/20_030_040_001_crowht_outtrafoI.pdf

http://213.156.45.208/primo/materiale/20_030_040_001_crowht_outtrafoII.pdf


The first article reports as reference a previos article that I'd like to have but seems very hard to find:

Crowhurst "How good ias an audio transformer?", published in Audio Eng., March 1952

Has somebody this last paper?

Thank You

AX has back copies of articles of Audio Engineering from 1947 through 1961. Sets of 30+ articles each are $ 16.95 each, but you would have to ask which set has that particular article.

Are U speaking of the "When Audio was Young" series? There isn't in, these books (valuable) are just a selection, not the real Audio Eng. collection, unfortunately.
Thank You

OK, thanks for the heads-up, good to know. I don't have them, but have seen them advertised and discussed.
