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.

XXXXitrons, XXXXphants

note slight error in figure 2 '-100V' should read 0V or ground (this
error was noted in a later issue)
This design has a very unusual method for preventing pitch drift.
