About the A1500 300B
The Allnic Audio A-1500 is a 300B single-ended (SE) stereo power amplifier, offering a high output power of 12.5 watts per channel. It utilizes an 'Inductor Drive' circuit, which allows for a swing voltage of up to 150V, resulting in very low distortion levels of about 0.3%. This circuit design helps to avoid the distortion often associated with conventional resistor-capacitor circuits used in other 300B amplifiers. The amplifier features sophisticated nickel alloy output transformers with high initial permeability, enabling fewer turns on the primary winding while maintaining high open circuit inductance. This results in a very wide frequency range and a low-distortion bass response. The A-1500 is designed to excel over other 300B amplifiers in terms of power output and sound quality.
