Loftin-White Tube Amplifier – SE Class A Stereo Amplifier

The Loftin-White is an outstanding SE (Single-Ended) Class A stereo tube amplifier, designed using the Loftin-White circuit topology (read more in our blog). This exclusive, Latvian-made amplifier is 100% handcrafted and built as a one-of-a-kind unit, making it a true collector’s gem for music enthusiasts.

The amplifier is constructed using point-to-point wiring technology, ensuring exceptional sound quality with minimal interference. The chassis is crafted from solid oak wood, elegantly integrated with metal details, combining natural aesthetics with premium materials.

Construction:

• Chassis: Made from solid oak wood and plywood, merging the natural beauty of wood with the elegance of metal elements for a classic and durable design.
• Tubes:
  • Power stage: Equipped with two 6C4C tubes, the Russian equivalent of the legendary 6B4G direct-heated triodes, widely used in high-quality audio amplifiers. Known for their warm, rich, and natural sound, 6C4C tubes are a favorite choice in Single-Ended (SE) Class A amplifiers. Their sound is smooth, musical, and highly detailed, with excellent midrange reproduction and low noise levels.
  • Preamp stage: Features two 6Г2 pentode tubes, equivalent to EF86, commonly found in vintage radios and audio equipment. These tubes provide stable and linear signal amplification, making them ideal for gain stages in SE and Push-Pull (PP) amplifiers. The 6Г2 tubes excel in delivering detailed high-frequency reproduction, ensuring crystal-clear and expressive sound.
  • Rectifier: The BO188 rectifier tube (kenotron) is used in the power supply section, delivering stable and clean DC voltage to the tubes. Compared to solid-state rectifiers, tube rectifiers help reduce power supply noise, enhancing overall sound quality. The BO188 minimizes electrical interference and ripple, ensuring a stable voltage supply, which is essential for the amplifier’s sonic performance.

Technical Specifications:

• Output power: 2 x 3W – suitable for small to medium-sized rooms with high-sensitivity speakers.
• Dimensions: Width: 37 cm, Height: 18 cm, Depth: 46 cm.
• Weight: 22 kg, providing stability and vibration reduction.

Sound Quality:

The Loftin-White amplifier is designed to deliver a warm, natural sound with outstanding clarity and musicality. The 6C4C power tubes produce a smooth, rich tone, while the 6Г2 preamp pentodes ensure precise signal amplification. The BO188 rectifier tube contributes to a clean and stable power supply, enhancing the overall audio performance. Together, these components create a harmonious and immersive listening experience, perfect for audiophiles and high-end tube audio systems.

Overall Impression:

The Loftin-White amplifier is a masterpiece, crafted for true audiophile enthusiasts who appreciate authentic, natural, and detailed sound. Its meticulous handcrafted construction and premium-quality components guarantee an exceptional listening experience while adding a touch of timeless elegance to any interior.
