Transaudio JC-2 Class A Preamplifier MAX Version Preamp (Silver) Supports Two Power Amplifiers

Circuit Features:
* MK JC-2 Class A amplification circuit
* Fully DC-coupled design: no coupling or feedback capacitors, resulting in a transparent and smooth sound
* Field-effect transistor input stage
* Output stage uses metal-can packaged triodes; operates with 20mA Class A current
* Dual-mono design: complete channel separation with zero crosstalk between left and right channels
* One RCA single-ended input
* Simultaneous dual output: RCA single-ended + XLR balanced — can connect to two power amplifiers
* True balanced output terminals (balanced wiring uses American standard wiring method)
* Ultra-minimalist design: ultra-short signal paths with all circuits affecting sound quality (like balanced input and source switching) removed

Materials & Components:
* All brand-new components
* 8-piece filter capacitor array
* Precision voltage regulation using original LM317 and LM337 for ON
* High-precision full aluminum housing
* 50W custom high-quality R-core transformer
* High-grade RCA terminals made in Taiwan: pure copper with gold plating
* Gold-plated IC sockets
* Original audiophile resistors for KOA
* High-quality printed circuit board: 2mm thick board with 70µm thick copper
