| The following four pages are the Hallicrafters' Service Bulletin
1951-30 which describes the installation of a shunt type noise limiter
and the installation of a crystal calibrator and a panadapter
connection. The bulletin is from August 6, 1951. Quality is not to great
because the original was printed on yellow paper and this scan was of a
copy (on white paper) of the original. Click the Back Button to return to the SX-28 article. |
