Mission Statement: The
purpose
of this website is to make available information in the following
categories:
1.
Out-of-Print documents, of historical interest, that are not
available elsewhere
2.
General-Purpose references that may be helpful in the examination
of
vintage equipment
----------------------------------------------------------------------------------------
Warning: The
information on this website comes from a time when safety concerns
were
minimal or did not exist. Vacuum tube electronics use high
voltages and currents that are dangerous, even potentially
deadly. The documents here are offered for historical or
reference purposes. If you choose to use this information to
work
on actual circuits you do so at your own risk.
