Hammond Model A, Руководство пользователя, Страница: 2 / 298

Foreword
to the
2016 Edition
This new edition exists to provide an alternative to the poor quality publications of
Hammond’s own HOOO-000495 master service manual that surfaced in various guises
during the late 70s - early 80s; as well as the even worse quality of the scanned material
found on the Internet as of this writing.
Hammond created the HOOO-000495 by making copies of copies, shrinking down
diagrams, and resetting certain paragraphs (often sloppily) to accommodate the inclusion
of models that were developed after the initial manuals had been written years before.
Every attempt has been made to be as accurate and authentic as possible to the original
manuals in terms of content and layout. Pictures have been replaced when possible (or
necessary) & sections clarified when needed. The format of this new, inclusive manual
follows more closely layout of the older versions from the 50s adding in the newer models
in the appropriate places. References to the Model BA were intentionally removed due to
lack of documentation of the “player” section. Also removed were any references to
buying new parts, as well as the Parts List itself due to their obsolescence.
The diagrams have been scanned at a 600dpi resolution from the oldest sources that
could be found. These older sources were typically fold out diagrams 17"x11" in size.
While they have been reformatted to 14"x8" to maintain continuity within the PDF format,
the high resolution of the scans allows for very clear zooming. Also included are some
diagrams and subjects that existed in the 40s & 50s literature, but were omitted from the
later 000495 manual.
This endeavor was done for the love of Hammond Organs and to assist in their
preservation. It is NOT meant to offer REVISIONS in the diagrams and schematics that
differ from Hammond originals. Hammond was very lax in offering revisions and often
they were the results of individual technicians based on their experience.
The manual is intended to be distributed FREE of COST.
Thanks goes out to the Audio Playground Synthesizer Museum for scanning the
Introduction section and getting the ball rolling.
Enjoy...
