About the SE100

The Golden Tube SE-100 is a stereo tube power amplifier delivering 100 watts per channel using EL-34 tubes in a Class A/B push-pull configuration. It can operate in three modes: two-channel fixed output, two-channel variable output, and bridged mono mode. The amplifier is praised for its very musical sound, well-balanced tonal characteristics, terrific bass response, silky smooth midrange, and extended highs. It is capable of using EL-34, KT-88, or KT-90 tubes for increased power output. The amplifier features easy bias adjustment knobs on top and can be biased with a basic volt/ohm meter. Users report outstanding soundstage depth and pinpoint imaging, especially when bridged into mono. While the company is no longer in business, the SE-100 remains a highly regarded amplifier on the used market, with repair and modification support available from reputable vendors. Some users note a slight hum or buzz typical of transformer coupling, and the amplifier may require careful tube selection and maintenance for optimal performance.
