Using double-sided immersion gold processes gold-plated circuit board!

Taiwan produced copper foot precision metal film resistors !

Siemens high-voltage filter capacitor!

Ceramic Gold-plated tube socket to ensure contact reliability!

Tube preamp circuit with ultra-low noise.

Because the second harmonic distortion is appropriate, the amplifier can be connected with more bile taste performance! Mellow sound performance.
