LL2.1 Deluxe

About the LL2.1 Deluxe

The Lamm Industries LL2.1 Deluxe is a premium line stage preamplifier designed to deliver exceptional audio quality. It features a single-ended topology with a gain of 18dB and operates in pure class-A mode from input to output. The preamplifier includes three single-ended inputs, one tape loop, and two sets of outputs. It also has a front panel muting switch and an attenuator for gain reduction by 15 dB. The power supply utilizes a custom-built Plitron toroidal transformer feeding a full-wave vacuum tube (6X4) voltage rectifier, followed by a choke-and-caps smoothing filter. The LL2.1 Deluxe is equipped with high-quality components such as Vishay/Roederstein and Electrocube film capacitors, Cornell Dubilier electrolytic capacitors, a Hammond filter choke, and milspec Dale resistors. The Deluxe version offers twice the power-supply capacitance of the standard model and uses polystyrene capacitors for enhanced performance. It is recommended to use this preamplifier with amplifiers having an input impedance of 10k ohms or higher.
