This is a
digitally copied and enhanced manual for the Precision model 660 cathode
conductance tube and transistor tester. It has been copied
from an original and is clear, clean, and easy to read. It is printed on premium 24#
paper with heavy covers and bound with a plastic comb. No more struggling with
unreadable photocopies!
It measures 8 1/2" X 11" with about 75 pages. Topics include:
introduction to transistor testing, basic 660 test circuits, introduction
to picture tube and crystal diode testing, operating instructions, service
data, tube test data information, transistor base indentification, and schematic. Also
included are three sets of tube data
for the models 640 & 660: Coletronics tube data TRC (H2B), Coletronics
tube data TRC (6-1-74), and Precision supplementary tube data TRC (GK)
including obsolete type, special applications, foreign tubes, and an
addendum to the TRC data (3-61) which includes American equivalents of
foreign types.
