The OPERLY Amp 2.0 SE12 amplifier is a high-quality stereophonic integrated power amplifier with EL-34 tubes in triode connection for a rich sound experience. It features a single-cycle circuit design with a short signal path and high-quality components.


The amplifier consists of two channels, each containing two amplifier stages made on two halves of a double triode 6H1П. It utilizes output transformers of its own production with a non-magnetic gap to prevent saturation.


The amplifier is housed in a closed case with solid wood front panels and includes a Soft Start system to prolong tube life. Technical specifications include a toroidal power transformer and channel-by-channel CLC filters.

The single-cycle circuit design with a short signal path and high-quality components in the OPERLY Amp 2.0 SE12 amplifier significantly impacts the sound quality. By minimizing interference and distortion along the signal path, this design preserves the integrity of the audio signal, resulting in clearer, more accurate sound reproduction.

Additionally, the use of EL-34 tubes in triode connection and output transformers of own production further enhances the amplifier's ability to deliver rich, detailed sound with warmth and depth. Overall, these design features work together to create an immersive listening experience that satisfies even the most discerning audiophiles.
