Perreaux PMF1155 Power Amplifier

Further Information:  Take a look at this unique find in our secondhand stable today, the Perreaux PMF1155 power amplifier. This unit is in excellent secondhand condition and stands as a testament to the enduring quality and performance of Perreaux audio equipment.

The Perreaux PMF1155 is a rare model in our estimation, so much so that it's the first we've ever encountered at Len Wallis Audio. Given our extensive history with Perreaux products, this speaks volumes about the rarity and unique value of the PMF1155. While information on this specific model is scarce, we believe it shares many of the outstanding qualities of its close relative, the Perreaux PMF1150B, known for its sweet, smooth sound and robust build.

Note: **if anyone has any insight or information on this model, we would be most interested!

The PMF1150B, and by extension the PMF1155, is celebrated for its dual mono Mosfet design, capable of delivering 100 watts RMS per channel into 8 ohms with exceptionally low total harmonic distortion. The careful selection and hand-assembly of MOSFET output transistors allow for superior sound quality and the potential for mono operation when bridged.

Key Features (based on the PMF1150B): 

 100 watts RMS per channel into 8 ohms, ensuring powerful and detailed sound reproduction.

Total harmonic distortion under 0.009%, the amplifier delivers pristine audio.

Features like a transient intermodulation distortion that's unmeasurable and a dynamic headroom with music of over 3.0dB make this amplifier stand out.

Designed for longevity, with a voltage swing per channel of 120Vp-p and a maximum current output of 7.5A continuous per channel.

Superior damping factor of over 500 from 10Hz to 1kHz, ensuring tight and controlled bass response.

Input sensitivity  equates to 1.5Vrms for the rated output at 1kHz, accommodating a wide range of audio sources.

Input Impedance of 47k ohms, ensuring compatibility with most preamplifiers.

Dimensions: 48.26 cm in width, 38.1 cm in depth, and 13.46 cm in height.

Weight: Approximately 15 kg, reflecting the solid construction and quality materials used.

Given its excellent condition and the rarity of the PMF1155 model, this offering represents a unique opportunity to own a piece of early 1980's audio history.
