About the I20 Single Ended
Triangle Art I-20 Single Ended Integrated Amplifier is a vacuum tube integrated amplifier built around a single-ended, zero-global-feedback, dual-mono design. It uses EL34 output tubes with 12AX7 and 12AU7 driver/line-stage tubes, and is specified at 20 W per channel in pure Class A. The amplifier emphasizes short signal paths, silver wiring, a heavy-duty chassis, a 2.5 mm thick PCB with a 4 oz solid copper plate, high-quality Mundorf capacitors, AMRG and Vishay resistors, and rhodium-plated PTFE-insulated RCA connectors. It was introduced as Triangle Art's first venture into single-ended amplification and is described as made in the USA.
