About this model
The surviving text is essentially the nameplate: Stromberg-Carlson model AU-58B, series 102, 25 watts, 50–60 cycles, for 105–125 volt mains only. The seller confirmed only that it powered up. The "AU" prefix also appears on the archive's other Stromberg-Carlson amplifier, the SAU-70, which suggests the same family of public-address units.
