Built to professional standards. Advanced industrial grade high capacity valves not used in any domestic amplifier, EAR amplifiers proven in studio use, accurate, simple, self-biasing, for user replacement of valves, when appropriate. In professional applications “XLR” input connectors and pure electronic balanced semi-floating inputs are supplied at a nominal additional cost. Stability - No feedback is used on the transformer secondary - The amplifiers are entirely stable into any load. Matched mono amplifiers are supplied in pairs for
