Tube synth diy

This is just part of a handtyped book from 1961, self-published in
Australia by T.K. Litchfield (B.Eng). Maybe it is the only copy?

I would like to scan the whole thing but it is too big for my scanner,
for now just the schematics and the references.

The book discusses additive and subtractive synthesis, timbre,
electro-mechanical and tube tone generators, harmonics.
