  • Hallicrafters S-40A (Runs 1-2) moved the Audio Transformer from the chassis top to the bottom.  The Rectifier tube was 80 for Runs 1-2; 5Y3 for Runs 3 and above.  The Speaker wires (2) were routed through a small hole and directly soldered in circuit.

    The following table lists some of the easy-to-identify differences of the S-40A 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. It is confirmed that the "(Runs 1-2)" model had a "U" version; it is unknown if the "(Runs 3 and above)" model had a "U" version.

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

    Other Original/B versions include S-40 (Original) and S-40B.

I have the part numbers for several manufacturers to replace the original "Can" capacitor on this model, but wondering where to search for the part numbers that I have available to me. 

The numbers are: Hallicrafters 45A062, Solar DY-400, Sprague El-344 & UT-8 and finally, Cornell-Dubilier UF43145C.

Seems like valuable information, but I don't have a clue how to look for these parts.  I suspect they are obsolete, but someone might have one.

Any thoughts greatly appreciated.
