Overview

The ACSA CB-700S is a vintage 23-channel CB transceiver produced during the 1970s Citizens Band radio era. Unlike many base stations of the time, the CB-700S is a solid-state mobile-style unit designed for 12 VDC operation. It provides standard AM communication on the 11-meter band and reflects the transition from tube-based equipment to fully transistorized designs.

Technical Specifications

Physical Description

The CB-700S features a compact metal mobile-style chassis designed for vehicle installation or small desktop use. The front panel includes a channel selector, volume and squelch controls, microphone connector, and an analog signal meter. Styling is consistent with mid-1970s mobile CB radios, typically with a dark faceplate, silver trim, and clearly labeled controls. The unit uses internal circuit boards rather than point-to-point wiring, reflecting its solid-state design.

History

The ACSA CB-700S was introduced during the peak of the 23-channel CB radio market prior to the FCC’s expansion to 40 channels in 1977. As manufacturers moved away from vacuum tube designs, radios like the CB-700S offered improved reliability, smaller size, and lower power consumption. ACSA is a lesser-documented brand, but surviving examples indicate it produced a range of CB radios during this period. Today, the CB-700S is mainly encountered in vintage radio collections.
