STR12A 12AU7/ECC82 Tube Remote Control Preamplifier HiFi Audio 4 In 1 Out Reference Cary SLP-90 Preamp Circuit

Product Details:

Refer to the American CARY-SLP90 circuit, this model is the pioneering work of the CARY triode tube pre-amplifier, and the response is great. Different from the traditional front, the SLP90 has high detail and thickness in the mid and low frequencies.

The remote control volume control board adopts 128-level relay pure resistance shunt control, the impedance is constant, the step is 0.5dB, and the total attenuation is 63.5dB. The resistance adopts American DALE/VISHAY precision resistance.

With audio output mute function.

With power-off memory function, it can return to the state before the last shutdown every time it is turned on.

With volume one-key return function..

Support 4 way stereo audio inputs, 1 way output.

Using 4 pcs PSVANE ECC82 tubes (optional).

Using pure copper gold-plated RCA terminal.

Using 30VA Hi end Oxygen-free copper R-core transformer.

Using Full aluminum chassis.
