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 at the end of 2024 in a fully triode 2A3 Push-Pull circuit. The construction uses the highest quality audio components, with an emphasis on purity of sound, operating stability, and uncompromising finish.
The equipment is 100% operational, quiet, stable, and plays beautifully — 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 (depending on bias)
Sound: natural, clear, with fantastic midrange and bass control
Case: brushed stainless steel + natural bamboo
Premium components • Zero compromises
Bulbs used in the construction
Power tubes:
4 × 2A3 Electro-Harmonix Gold – matched pairs, selected sets
Driver stage:
4 × 6SN7C Psvane Classic Series
All tubes are in excellent condition, with low usage.
Components and construction
Output transformers, mains transformer and choke: Toroidy.pl (Mr. Lachowski)
Polypropylene audio capacitors – selected
Input jacks and speaker terminals: gold-plated
Tube sockets: ceramic, gold-plated contacts
Grounding arranged in a topology that minimizes noise (no hum)
High-voltage power supply
electronically regulated
Gradual voltage rise (soft start)
Delayed load connection
Rectifier tube 5C3S
This is a rarely seen solution in DIY — a huge improvement in tube life and operating 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 of 2A3
Wide and deep soundstage
Dynamics clearly better than 2A3 SE
Fast, controlled bass
High level of detail without harshness
The amplifier works very well with high-efficiency speakers (e.g., tube, full-range, coaxial).
Condition and usage
Construction completed in late 2024
Used sporadically, mainly for testing
100% functional, stable, quiet
No faults, no hum, tubes in excellent condition
