  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.
