Description: The Horn Mono Amplifier is designed specifically for use with very efficient loudspeakers. It has extremely low noise and distortion as well as having 18db less gain that Quicksilvers standard amplifiers. This avoids the noise and gain problems that normally appear when using horn speakers. The amplifier is designed to sound good at the extremely low levels (milliwatts) that horn loudspeakers require. Many amplifiers actually have higher distortions at these low levels.
As with all Quicksilver amplifiers many different output tubes may be plugged in directly with no adjustments: Matched pairs of EL34, KT90, KT88, KT77, KT66, 6550, or 6l6 output tubes. The power supply has over 100 joules of storage. 25 watts into 4 or 8 ohms.
