L.A.Barreiros - Atelier - Dual Retifier Solid state amplifier

Solid-state amplifiers (based on NAIN) manufactured at L.A. Barreiros - Atelier in 1995 and were among the first models produced by this hi-fi workshop. They operate with a separate low-frequency power supply (dual rectifier), having no interference of any kind, delivering a sound up to 85W/8 ohms with no noise and with excellent quality. They can drive 150W speakers without issue. The front knobs are signal attenuators for the preamplifier that sends the signal, so there is no zero volume but rather the minimum value that the preamplifier outputs. As these were among the first works of this atelier, they have some artisanal finishes, but always using high-quality materials and terminals.
