The Audio Note (UK) Vindicator Stereo Power Amplifier is a Pure Class A Singled Ended valve amplifier that uses the 2A3 triode valve, which is known for its exceptional sound quality and musicality. The 2A3 triode valve is a relatively low-powered tube that operates in Class A mode, which means that it is biased to conduct current continuously throughout the entire waveform. This results in a very linear and distortion-free amplification of the audio signal.

The Vindicator Stereo Power Amplifier has been designed and engineered with a focus on achieving superior sonic performance rather than just meeting technical specifications. It fulfills all of Audio Note (UK)’s Level 3 criteria with pure Class A operation with the output transistors biased to conduct current continuously throughout the entire waveform. This results in a very linear and distortion-free amplification of the audio signal. Zero Negative Feedback, which allows the amplifier to deliver a more natural and musical sound. Single Ended Output Stage using a single output transistor to amplify the audio signal. Valve Rectification, which uses vacuum tubes to convert the AC voltage from the power supply into a DC voltage that can be used to power the amplifier. Directly Heated Triode operation and the use of materials and component quality throughout, including custom-made transformers, high-grade capacitors, and precision resistors. The amplifier also features a hand-wired point-to-point construction that minimizes the use of circuit boards, which can introduce unwanted noise and distortion.

The Silver version of the Vindicator Stereo Power Amplifier builds upon the already excellent performance of the standard Vindicator by incorporating Audio Note Tantalum film resistors for their high precision, stability, and low noise, resulting in a more precise and transparent sound, Audio Note (UK) Copper Foil signal capacitors, which bring exceptional sound quality and ability to deliver a more natural and musical sound compared to other types of capacitors, and IHiB C-core output transformers. These component improvements are intended to take the already excellent performance of the standard Vindicator to an even higher level.

The Vindicator is also available as Silver Signature version offering an outstanding performance featuring Audio Note (UK) Copper Foil signal capacitors, Audio Note (UK) Tantalum film resistors, and Audio Note (UK) SHiB Double C-core output transformers.
