Emoryseric Tube Preamplifier, WADA Shigeho Circuit Audio Preamp, Oil-Immersed Capacitors, Hi-Fi Stereo Tube Amplifier for Home Audio System (Silver/Single Transformer/RCA/No Tubes)
- Optimized Wada Shigeho Circuit: Implements an advanced SRPP (Shunt Regulated Push-Pull) output stage instead of traditional cathode followers. This design delivers lower output impedance, enhanced driving capability, and significantly improved high/low-frequency response while maintaining warm mid-range vocals.
- Premium Oil-Immersed Filtering: Features a sophisticated three-stage RC high-voltage oil-immersed capacitor filtering system, combined with a Field Effect Transistor (FET) voltage regulation circuit. This ensures ultra-low ripple, pure power supply, and exceptionally smooth, detailed audio performance.
- Dual-Transformer Independent Architecture (Optional for Dual-Transformer Spec): The dual-transformer version utilizes an independent power supply for left and right channels to eliminate cross-talk, achieving remarkable channel separation, an expansive soundstage, and dynamic transient response.
- Flexible Tube Compatibility: Equipped with built-in manual jumper switches, allowing seamless switching between 6Z4 and 6X4 (EZ90) rectifier tubes without requiring external adapters. Compatible with standard dual-triode tubes like 12AX7 and 12AU7/12AT7 for versatile sound tuning.
- High-End Components & High SNR: Built with a low-leakage R-core transformer, a full-aluminum chassis, solid aluminum knobs, and high-purity signal wiring. Effectively suppresses background noise (92dBu SNR) to deliver a transparent, pure analog sound.
