Rotel RC-850 and RB-850 Pre and power amplifiers Dual Mono with Moving Magnet (MM) and Moving Coil (MC) cartridges

The Rotel RC-850 and RB-850 are a classic, highly regarded audiophile preamplifier and power amplifier combination released in the late 1980s (manufactured roughly between 1987 and 1991). Known for their minimalistic design and "giant-killer" performance, this budget-friendly British-designed duo punched far above its price weight class by prioritizing sound quality over flashy features.

Rotel RC-850 Preamplifier Overview

The RC-850 is a flexible, straightforward preamplifier designed to cleanly route signals without coloration. [1, 2]

Phono Stage: Features an excellent internal phono stage supporting both Moving Magnet (MM) and Moving Coil (MC) cartridges, which was rare for budget gear at the time.

Independent Controls: It lacks a traditional balance knob. Instead, it utilizes two friction-locked, concentric volume knobs that can be adjusted independently. [1]

Tone Control Bypass: Includes a front-panel switch to completely bypass the bass and treble circuitry, providing a shorter, cleaner signal path for purists. [1]

Outputs: Dual line-level outputs and gold-plated inputs for critical sources like CD and Phono. [1]

Rotel RB-850 Power Amplifier Overview

The RB-850 is a robust power amplifier built with an emphasis on a strong power supply. [1, 2]

Power Output: Delivers 50 watts per channel into 8 ohms.

Dual-Mono Architecture: Internally, it features twin power transformers and a true dual-mono layout. This design yields an exceptional bass response and excellent channel separation.
