Riviera Audio AFM70 – a Powerful Hybrid Amplifier
Riviera Audio Labs has released a new monophonic power amplifier Riviera Audio AFM70, which develops up to 70 W into an 8 Ohm load and up to 140 W into 4 Ohms. These are very solid figures for the hybrid amplification circuit used here – a vacuum tube is used in the preamplifier stage, and the output stage is built on semiconductors.
