Experience the emotion and essence of music with the Neo-Classic 250 Monoblock Power Amplifier. This amplifier, built on decades of circuit refinement and proven componentry, maximizes a classic push-pull design for a rich and powerful sound. You can choose between the sonically seductive qualities of triode mode or the more powerful Ultra-Linear configuration. The Neo-Classic 250’s big, beefy capacitors ensure dynamic performance and powerful bass impact.


Key Features:

  • Dual Mode Operation: Switch between triode mode for a three-dimensional, seductive sound, and Ultra-Linear mode for powerful, full-bodied performance.
  • High-Quality Components: Utilizes 10 Tungsol EL34B output tubes and big capacitors for dynamic performance and powerful bass.
  • Soft-Start Mode: Minimizes in-rush current with a "Soft-Start" mode, also featuring an "Ever-Warm" position to keep the amplifier ready for use.
  • Custom Transformers: Designed and wound in-house at Manley Labs for superior sound quality.
  • Front Panel Controls: Convenient bias measurement and adjustment, along with a mute switch for easy operation.


Design and Evolution:

The Neo-Classic 250 builds on the legacy of the Manley 500 and 250 Watt Monoblocks, which have been refined over years of development. These amplifiers offer reliability, musical accuracy, and emotional authority. The 1998 redesign of the output transformers aimed to reclaim the rich mid-range of vintage designs, while the 2013 rework optimized the Ultra-Linear mode for a balanced, powerful sound. Extensive listening tests and measurements have ensured a stunning result that delivers deep bass and low distortion.
