About the SE34i

The Tec On Audio SE34i is a hand-built, single-ended triode integrated amplifier designed for audiophiles seeking high-fidelity sound with EL34/6CA7 output tubes. It features a self-biasing, self-balancing design that eliminates the need for manual bias adjustment, ensuring matched output power and superior sound quality. The amplifier offers around 5 to 8 watts RMS per channel into 8 ohms, depending on the model and tube configuration. It uses high-quality custom-wound UFO output transformers and copper foil Mylar coupling capacitors for enhanced sonic performance. The chassis is powder-coated steel, providing durability and mass for reduced vibration. The amplifier supports multiple tube wiring modes (true triode and pseudo-triode) and can drive a variety of speaker impedances, including planar magnetic headphones. It includes multiple input jacks and binding posts for flexible speaker connections, including bi-wiring and bi-amping options. The SE34i is known for its quiet operation with virtually no hum and offers a choice of wood bases and knob types. It has been produced in several revisions from 1996 through 2022, with improvements such as upgraded transformers, capacitors, and compatibility with various output tubes like KT77, KT88, and 6550. The amplifier is made in the USA and comes with a lifetime warranty.
