PRT12A Tube Preamplifier Tube Preamp (AC 230V Input with PSVANE ART 12AU7-S Vacuum Tubes) + Remote

PRT12A Tube Preamplifier Tube Preamp (AC 230V Input with PSVANE ART 12AU7-S Vacuum Tubes) + Remote

Features:
* It is based on the American CARY-SLP90 circuit. CARY-SLP90 represents CARY's pioneering work in tube preamplifiers, featuring fast response. Compared with traditional front-end designs, the SLP90 offers high detail and richness in the mid and low frequencies.
* The remote volume control board uses a 127-step relay-based pure resistive shunt control, maintaining constant impedance, with 0.5dB increments and a total attenuation of 63.5dB.
* It includes an audio output mute function.
* It features a power-off memory function, allowing the unit to return to the previous state each time it is turned on.
* It offers a one-key volume return function.
* Supports 4-channel stereo audio input and 1-channel output.
* Uses 4 PSVANE ART 12AU7-S vacuum tubes.
* Employs pure copper gold-plated RCA terminals.
* Equipped with a 30VA high-end oxygen-free copper R-core transformer.
* Constructed with an all-aluminum chassis.
