Vieta - A-225 放大器与 B-4000 喇叭 Hi-fi 音響組

Vintage Audio Lot – Vieta A-225 Vacuum Tube Integrated Amplifier (1972) + Pair of Vieta B-4000 Speakers (3-way, 4 drivers) – Made in Barcelona

This set represents an exceptional opportunity in the vintage audio market. For its exquisite point-to-point circuit architecture and its Push-Pull configuration with Siemens EL84 tubes, this Vieta A-225 offers the same three-dimensional warmth, dynamics and build quality as the legendary British or American amplifiers of the era (such as the mythical Leak Stereo 20, Rogers HG88 or Dynaco SCA-35), but with the advantage of maintaining a much more competitive price. A true "sleeping giant" of European High Fidelity of the 70s, fully serviced, noise-free and ready to enjoy from day one.

As a great added value, the lot includes a modern Bluetooth tube-based Receiver/Preamplifier. This device allows wireless connection of mobile phones, tablets or laptops (Spotify, Tidal, etc.) directly to the system, enjoying digital convenience without sacrificing warmth, aesthetics and purely valve sound.

Magnificent audio set from the Spanish high-fidelity golden age. This lot includes an iconic valve stereophonic integrated amplifier Vieta A-225 and a pair of Vieta B-4000 speaker cabinets, both designed and manufactured in Barcelona in the early 1970s. A mythical, highly sought-after combination by audiophiles due to its sound warmth and purely analog aesthetics.

1. Vieta A-225 Valve Amplifier (Details from Internal Photos):
• Year of manufacture: 1972
• Power: 19W RMS per channel with valves.
• Components and originality: As seen in the detailed interior and top chassis photos, the unit retains excellent originality. It features the coveted era components such as Bianchi brand components, 64 µF axial Fabor capacitors and the original Fagor B60 C200 rectifier bridge. A historic piece with no strange modifications or aggressive modern recaps that would alter its vintage essence.

• Tube and Transformer Section: Equipped with EL84 power tubes from Siemens (Made in Germany) visible in the captures, along with their original oversized output transformers free of severe rust. Preamp section shielded with its aluminum protective caps for ECC83.

• Technical condition: Good functioning. The amplifier powers on and delivers clean sound on both channels. Preventive maintenance has been performed with cleaning and technical lubrication of potentiometers (applied Lubrilimp-1 professional spray). The knobs operate cleanly and without noise; the bass potentiometer retains the firm, dense touch characteristic of the original component, functioning correctly across its entire range.
(no changes made to preserve originality)
• Aesthetic condition: Good general condition with normal signs of use due to age.

2. Vieta B-4000 Speakers.
• Type: Passive 3-way speaker cabinets with 4-driver configuration (1 x 10" woofer, 2 x 3.5" mids, 1 x tweeter).

• Allowable Power Handling: 45 W RMS / 50 W Continuous (peaks up to 100 W Musical without clipping).
• Sensitivity / Efficiency (dB): 89 dB SPL (measured at 1 W at 1 meter in anechoic chamber).
• Technical note: 89 dB is an excellent sensitivity for vintage cabinets of this size. This means they are highly efficient speakers, perfect to maximize and sound powerful using the 19W RMS per channel delivered by the Vieta A-225 tube amplifier, producing a sense of volume, body and dynamics equivalent to a modern 50–60 W transistor amplifier.
• Nominal Impedance: 8 Ohms (Ω).
• Frequency Response: 35 Hz – 22,000 Hz (providing complete coverage from deep bass to very crystal highs).

• Solid wood enclosures in good aesthetic condition. Grilles have been fully restored by installing new period green fabric. Additionally, the mounting system has been improved: instead of fixed nailed installation, a high-strength Velcro mounting system has been implemented. This allows easy and clean removal of the grilles to display the components without damaging the wood.
• Sound: They offer a very balanced response, with natural bass and very present mids ideal for jazz, classic rock and analog music.
• Condition: Rear connectors operational.

3. Included Extra: Bluetooth Tube Receiver/Preamplifier:
• Function: Acts as a modern digital-analog bridge. It connects to the auxiliary input of the Vieta A-225.
• Aesthetics: Features two illuminated tubes on top and a brushed aluminum front panel that harmonizes perfectly with the Vieta amplifier design.
• Connectivity: Integrated rear antenna for stable, long-range Bluetooth reception. Auxiliary input and output via gold-plated RCA connectors.

Shipping terms:

Due to the scale, total combined weight and extreme delicacy of the components (especially transformers and glass vacuum tubes), the lot will be shipped in 3 separate packages:

this set is the "Holy Grail" of Spanish vintage audio from the 70s because they complement each other perfectly. The sound is warm, with rich mids and a round bass that only comes from combining the sweetness of EL84 tubes with the generosity of a 10-inch woofer like the B-4000.
