Choke coupled phase invertor

Gentlemen,

RDH4, chapter 7.2 (xii), p. 355, Fig. 7.51D mentiones a choke coupled phase inverter, along with a few lines of explanatory text. A reference is made to this article:

Seymour, R. A., and D. G. Tucker "A choke-coupled phase-invertor of high accuracy"
Electronic Eng. 23.276 (Feb. 1951) 64.

I am searching for this article. Google says it should be available at pearl.com, but it is only mentioned in an index.

I tried to contact Jeremy Epstein but w/o success, who built an amp using such a splitter: http://home.earthlink.net/~jeremyepstein/ironconcertina.html

If someone has access to the original Seymour/Tucker article, it would be nice if I could get a scan/copy.

Tnx2u,

Tom
