Description from the seller
Tube Amplifier 2A3 Push-Pull High-End • Handmade 2024 • Psvane • EH Gold
For sale I offer a high-end tube amplifier, handmade in late 2024 in a fully triode Push-Pull topology using 2A3 tubes. Construction from top-quality audio components, with emphasis on sound purity, operational stability, and uncompromising finish.
The equipment is 100% functional, quiet, stable and sounds stunning — open, natural, with very good bass control (a rare feature in 2A3 amplifiers).
Key features
Two-channel stereo amplifier in 2A3 Push-Pull configuration
Power: 2 × 15–20 W (depends on bias)
Sound: natural, transparent, with fantastic midrange and bass control
Cabinet: brushed stainless steel + natural bamboo
Premium components • Zero compromises
Tubes used in the construction
Power tubes:
4 × 2A3 Electro-Harmonix Gold – selected sets, matched in pairs
Drive stage:
4 × 6SN7C Psvane Classic Series
All tubes are in excellent condition, with low mileage.
Components and construction
Output, mains transformer, and choke: Toroidy.pl (Mr. Lachowski)
Polypropylene audio capacitors – selected
Input sockets and speaker terminals: gold-plated
Tube sockets: ceramic, gold-plated contacts
Grounding arranged in a topology that minimizes noise (no hum)
High-voltage supply
Electronically regulated
Slow ramp-up of voltage (soft start)
Delayed load connection
Rectifier tube 5C3S
This is a rarely seen solution in DIY — huge improvement in tube life and stability.
Technical specifications
Output power: 2 × 15–20 W
Frequency response: 8 Hz – 54 kHz
Output impedance: 6 Ω
Recommended speakers: 6–8 Ω
Bias adjustment: external, manual (fixed bias)
Maximum input level: 2 V
Sound character (subjective)
beautiful, organic midrange typical for 2A3
wide and deep soundstage
dynamics noticeably better than 2A3 SE
fast, controlled bass
high detail without harshness
The amplifier works great with high-efficiency speakers (e.g., tube-friendly, full-range, coaxial).
Condition and usage
construction finished in late 2024
used sporadically, mainly for testing
100% functional, stable, quiet
no faults, no hum, tubes in excellent condition
