LEAK "Point One" Amplifiers
by H.J.Leak, Published 1951.

In late 1951 H.J.Leak & Company published a 28-page treatise explaining the history, concept, and design of the TL/12 amplifier and the associated RC/PA/U pre-amplifier.

This pamphlet makes for fascinating reading for anyone interested in the history of the valve amplifier development during the "golden age" of audio (from the late 1940's to the early 1960's).

Unfortuantely the pamphlet is very rare, but a facsimile of it is now available from this Web page. The original formatting and typesetting has been retained as much as is possible within the constraints of Web-distribution. As the only copy available was a photocopy, the quality of the photos is not as good as the original (which even featured gold-printing on the cover, and also for the photo of the amplifier on the first page).

(Original photo of the "Leak Point One Amplifiers" Booklet provided by Bruce Scahill of New Zealand.)
