Shure - SR105C-E6 Audio amplifier

The Shure SR105 power amplifier is a high-powered amplifier designed for sound reinforcement applications. Made in the United States, this amplifier exemplifies Shure's commitment to quality and enduring performance. This vintage amplifier has no custom alterations. The power amplifier provides both direct speaker-coupled output and a constant-voltage output coupled to a 70-volt transformer. The amplifier is of rugged construction designed to provide reliable operation at high power levels with minimal distortion and phase shift. The high‑power sound reinforcement system can be assembled for use with a variety of speaker systems. The 70‑volt output feature of the amplifier makes it equally adaptable to either source-oriented or distributed speaker system configurations, such as those used for background music or announcements in warehouses, institutions, or public places. A voltmeter on the amplifier facilitates adjustment and control of the output level. Supplied with the portable carrying case accessory A105A. It shows signs of use, as can be seen in the photographs, but it works perfectly.
