Product Details:
The X20pro amplifier delivers rich tube character, exuding elegance, refinement, and clarity, reviving the classic sound of the Western Electric WE91.
2A3 launches 211 single ended A-class electronic tube amplifier, which not only retains the soft tone of 2A3, but also achieves higher power output through 211, suitable for music enthusiasts who pursue high fidelity and large dynamics.
UMade purely by hand, with shed welding.
The amplifier part replicates the Western Electronics 91 circuit, uses 310A for voltage amplification, and drives the transformer through 2A3 Power amplification output by 211 electron tube.
Set the 310A electronic tube filament delay power supply to ensure the safety of the 310A filament.
Specially designed large loop and small loop feedback working modes, the sound is thick, smooth and pure when the large loop is working, and the sound field is lively when the small loop is working.
Mundorf Mcap, SOLEN PB-MKP-FC and other coupling capacitors, LSTL, Nichicon, SANYO filtering capacitors, combined with blocking coils, provide low ripple and large capacity electrical energy reserves.
External power transistor current adjustment potentiometer, VU meter with selectable current display and output level.
Japanese ALPS high-end motor potentiometer.
Power on high voltage delay and mute delay function (approximately 30 seconds).
The preamp part uses 2 Russian 6SN7 and 2 replica Western Electronics 310A electronic tubes each.
The driving part adopts 2 2A3 and 2 cross-linking transformers coupled to the power amplifier, with elegant and delicate sound, beautiful and ethereal, and abundant dynamics.
