• Bemerkung

• Hallicrafters S-40 (2nd Revision) used a Permanent Magnet (PM) Speaker.  The chassis Speaker Socket and the Speaker cable assembly Plug were deleted.  A grommet was installed in place of the Socket on the chassis and the Speaker wires (2) and Audio Transformer wires (2) were routed through the grommet and directly soldered in circuit.

  The following table lists some of the easy-to-identify differences of the S-40 versions.

  Additional circuit differences (resistors, capacitors, wiring) are not described here; refer to the schmatics for additional differences.  Note that the "U" model used a Universal power transformer (120/240 volts; 25-60 Hz) for export and it is unknown which S-40 versions had a "U" version.

  Refer to S-40 (Original) for the Guide to Identifying Hallicrafters S-40 Versions document.

  Other A/B versions include S-40A (Runs 1-2) and S-40B.
