I forget to mention that the article is in the edition of the handbook
copyrighted in 1962.
I hope that helps.
A detailed construction article about to build a W9TO keyer may be
found in Bill Orr's "West Coast" handbook on pages 597 - 600. The unit
in the handbook seems to have a circuit that is identical to the T.O.
keyers commercially manufactured by Hallicrafters.
