Tonewinner AD-89D: high-fidelity architecture and design

This Tonewinner amplifier adopts a high-speed, low-distortion Class A amplifier circuit with strong drive capability and beautiful dynamics. It's also worth mentioning that the internal structure separates the power stage from the input and signal processing stages. Left and right channels are also processed independently. This structure greatly reduces the risk of interference and noise generation. On the power supply side, the AD89-D uses a 350VA toroidal transformer and 40000uF capacitors. No less than 8 high-precision, high-power matched tubes are used for the output stage.

Tonewinner AD-89D: from integrated amplifier to power amplifier

U-shaped rings on the AD-89D's connectors enable it to be used as an integrated amplifier. Removing these rings simply allows it to be used as a pure power amplifier within a complete sound system. This amplifier's immense versatility means it can meet most of your needs.
