ML1

About the ML1

The Lamm ML-1 monoblock power amplifier represents a new generation of tube amplifiers using unique high current low impedance 6C33C-B triodes in the output stage, allowing for a low turns ratio output transformer with extended frequency response and reduced leakage inductance. It delivers 90 watts per channel into 8, 4, or 2 ohms with a frequency response of 20Hz-20kHz (-0.3dB) and up to 82kHz (-3dB). The amplifier uses a hybrid topology combining vacuum tubes (two 6C33C-B, one 12AX7WA/7025, one 12BH7A) with high-frequency MOSFETs for linearity and low distortion. It features two multifunction meters for bias and balance control, RCA and XLR inputs, and gold-plated Neutrik connectors. The ML-1 is hand-built with premium components including military-grade resistors and capacitors, and a toroidal power transformer suspended in a vibration-absorbing encapsulant to ensure clarity and microresolution. It weighs 70 lbs and measures 16" W x 8.25" H x 21" D. The amplifier is praised for its speed, resolution, naturalness, and bass depth, making it a no-compromise high-end tube amplifier.
