Model 3000 Series 2 control pre-amplifier

In very good condition, recently serviced at Len Wallis Audio.

Description

The Model 3000 is a state-of-the-art preamplifier using modern solid-state technology. From its fully shielded, tightly regulated power supply to its unique gold-plated, tactile feel push buttons, the creativity and craftsmanship of the 3000 are evident.

Touching a push button or turning a knob will convince you of the precision and quality of the components used to make the Model 3000 not only elegant to look at, but a pleasure to operate.

Innovative features of the preamplifier include its CMOS Logic Memory System used to control relays for all critical switching, two independent RIAA phono stages for elimination of all low level switching, built-in head amp for moving coil cartridge reproduction, stepped attenuator volume control, and Noise Reduction input/output jacks for installation of outboard noise processors.

Only the highest quality components have been used to assemble the Model 3000, including 1% metal film resistors, 2% polystyrene capacitors and solid tantalum capacitors; all to guarantee the high performance specifications for the life of the unit.

Quality is not limited to just electrical components, but extends to the rugged 20 gauge cold-rolled steel chassis for minimization of magnetically induced interference, to the solid glass-epoxy, double-sided printed circuit boards, to the deep-grained, 3/16 inch thick front panel, and to the oversized 16 gauge line cord.

Considerable design effort has been put into the Model 3000 to separate fact from aural fantasy, with regard to audio reproduction.

Use of third-generation integrated circuits creates virtual immunity from overloading caused by either steady state or transient effects, whether amplitude, frequency or slew induced. Absolute minimizing of non-linearities and noise allows a clarity and accuracy of sound reproduction unsurpassed.
