The following pages contain full size drilling templates for many of the circuits in the Manual. It is a good idea to mount each template on cardboard before it is used so that it will not tear readily and become unsatisfactory for repeated use. The template should be securely fastened to the circuit board before holes are drilled through it. A key to the symbols used on the tem plates is interspersed among the following pages. A list of templates is given below.
