    Hi all, I did manage to find a Hallicrafters 38 after some looking and also scored some Vintage “Brush” brand headphones. The headphones are 2 wire to fit the Hallicrafters, but they are shot. I opened one side up which was tricky as they are bakelite. Nothing but bits of the active crystal and shorted wiring. I need to find some tiny speakers for them (smaller than 40 mm wide). The radio main speaker is 3.2 Ohms and the only tiny speakers I can find are the ones in the link below. Will these work? they are the right size otherwize. Any other places to look for the parts?

    Gary,

    The par of Hallicrafters headphones in the attached picture are 3500 ohms measured at the 1/4 inch plug.
    I do not know what difference the impedance would make.
    They do click in the ear pieces with the ohm meter leads.

    Hi John, Those must be later as they have the single large plug. My S38 is the first year (1946) model and has the older 2 pin type socket. The headphones were rattling, so I opened one side and parts and pieces fell out.
    I sort of suspected that as they were cheap and tested open on both sides. I’m trying to slide in modern replacements as there is no prospect of fixing them. here’s a pic

    Thanks, Gary
