From Arthur E. Thiessen, A History of the General Radio Company (1965):
Later [in 1948], recognizing the need for simple, wide-range, basic, laboratory instruments, particularly, for instance, in schools and colleges, GR introduced the so-called Unit line, a concept of Eastham, developed by Karplus.
Precision laboratory instruments are rather costly, especially in terms of college teaching budgets, but by the careful use of cost-cutting design and manufacturing procedures, good instruments adequate for many purposes can be produced.
The first of a long line of Unit instruments made with these considerations in mind were a wide-range oscillator (1207-A) and an amplifier (1206-A).
The power supply for them (1205-A) was a separate unit, suitable for either, so that one supply could be purchased to power either of them and, later, many other Unit designs for a variety of uses.
