Oldchen 300B Tube Amplifier, Single-Ended Class A Integrated Amp, Hand-Wired Point-to-Point, 9W*2, Dual VU Meters, 300B-SE / 6SN7GT / 5U4G Tubes (Silver, Upgrade Version)

A Decade of Refinement in Every Connection
This amplifier is not a mass-produced item; it is a product of over 10 years of dedicated refinement. Each unit is meticulously built using hand-wired, point-to-point soldering, a technique revered for its superior sound quality and durability. The clean, optimized layout is a testament to this experience, and all signal paths use high-end Teflon silver-plated wire to ensure the purest possible signal.
The Sound of Silence: Innovative Low-Noise Design
A common challenge for 300B amplifiers is noise. We have engineered a definitive solution. This amplifier incorporates two dedicated PCBs for the 300B tube filament power supply. This modern hybrid design isolates the sensitive filament circuit, resulting in an exceptionally low noise floor—as low as 0.2mV. The audible result is a "black" background where music emerges with stunning clarity and improved bass definition.
Built with Only High-Quality Components
Power Supply: A custom-wound, low-leakage Z11 iron core transformer works in tandem with a heavy 5H pure copper CLC choke to provide exceptionally clean and stable power. Potentiometer: A genuine Japanese ALPS potentiometer ensures smooth, precise volume control with no channel imbalance.
Capacitors & Resistors: The circuit uses a curated selection of audiophile components, including capacitors, and high-precision metal film resistors from Taiwan.
Terminals: All tube sockets and speaker terminals are gold-plated to ensure a perfect, long-lasting connection.
Tube Options: Standard vs. Globe
We offer two versions to suit your preference:
1. Standard Version: Comes equipped with a full set of Psvane tubes: 2x 300B-SE, 2x 6SN7GT, and 1x 5U4G rectifier.
2. Globe Version: Upgrades the preamp tubes to premium Psvane CV181-SE and the rectifier to a high-end Psvane 274B, offering an even more refined, high-resolution sound.
