The Snapper achieves true 100 watts output at 10 Hz with 110 watts maintained across the entire critical frequency range from 15 Hz to 40 kHz. This extended full-power bandwidth results from a proprietary 19-section output transformer, designed and wound in-house at Manley Labs. The complex transformer architecture ensures deep, controlled low-frequency response and extended high-frequency clarity, even at maximum output levels, delivering consistent performance across the audio spectrum. In short, they go an octave lower than most amps you have heard!

Manley Snapper® - all-tube mono blocks that need to be heard!
The Manley Snapper mono-blocks deliver 110 watts of vacuum tube power with the dynamic authority and tonal refinement that define high-performance amplification. Combining push-pull EL34 output stages with fully differential input and driver circuitry, the Snapper amps provide control over demanding loudspeaker loads while maintaining the natural, three-dimensional presentation characteristic of well-engineered tube amplifiers. Hand-built in California, each mono-block embodies precision construction and sonic integrity for discerning listeners. Most studios these days run active speakers, but if you have a chance to drive some quality passive loudspeakers with these amps, you have to experience this amp to fully appreciate it.
Differential signal path with versatile input topology
The Snapper amps employ fully differential circuitry throughout the input and driver stages, enabling true balanced operation via XLR inputs without input transformers. This differential topology maintains signal integrity from input to output while rejecting common-mode noise and interference. Unbalanced RCA inputs are offered as well, providing seamless integration with any HiFi preamplifier while preserving the amps' sonic character and low-noise performance.
Accessible maintenance with extended tube service life
All biasing controls and measurement points for the EL34 output tubes are positioned on the top deck for convenient access during routine maintenance. Following Manley's design philosophy, the Snapper operates with high plate voltages at moderate current levels, optimizing both sonic performance and tube longevity. This approach ensures reliable operation and extended service intervals while maintaining the dynamic capability and tonal accuracy that distinguish vacuum tube amplification.

Frequently Asked Questions
The primary advantage of the monoblock design is the complete physical and electrical separation of the left and right audio channels.
A fully differential circuit topology means that the amplifier's input and driver stages are designed to process the positive and negative phases of the audio signal independently and symmetrically. This is particularly advantageous when using the Balanced XLR inputs, as it maintains the integrity of the differential signal all the way through the input stage without the need for an input balancing circuit. This results in superior noise rejection and a purer signal path.
Manley recommends checking the bias settings on the EL34 output tubes periodically to ensure optimal performance and long tube life. A good rule of thumb is to check the bias every few months, especially after the first few hundred hours of use. The Snapper makes this process straightforward, as all bias measurement points and adjustment trimpots are conveniently located on the top deck of the chassis. The target bias is 300 mVDC.
The significance of the 19-section output transformer lies in its high performance and complexity, which is crucial for achieving the Snapper's full power bandwidth. This proprietary transformer, designed and wound in-house at Manley Magnetics, is essential for ensuring that the amplifier can deliver 110 watts with full fidelity from 15 Hz all the way up to 40 kHz. Its sophisticated design ensures accurate signal transfer and deep, controlled bass, even under continuous, high-power demand.
Yes, the Snapper is designed with a robust output stage and high-current drive capability, making it well-suited to handle a variety of speaker loads. While its performance is optimized for a 5 Ohm load, its actual output impedance is low (1.5 Ohms), providing the necessary damping factor and control to drive most low-impedance loudspeakers with excellent bass impact and dynamic authority.
The Manley Snapper is designed and optimized for use with the EL34 or the 6CA7 (6CA7 EH) output tubes.
