Physical Description
The CBRI-805 is housed in a metal cabinet designed for desktop base station use. The front panel typically includes channel selector controls, volume, squelch, and tuning adjustments, along with an analog signal meter. The styling follows mid-1970s conventions with a combination of painted steel and brushed metal finishes. Internally, the radio uses point-to-point wiring with vacuum tubes, transformers, and discrete components mounted on a steel chassis.
History
The ACSA CBRI-805 was produced during the peak of the 23-channel CB market prior to the FCC expansion to 40 channels in 1977. ACSA-branded equipment is less commonly documented than major manufacturers, but models like the CBRI-805 represent standard consumer base stations of the period. Surviving examples are primarily found among collectors and vintage radio enthusiasts.
