Conrad-Johnson ART88 Reference Preamplifier

LIMITED EDITION CONRAD-JOHNSON ART88 DUAL-MONO PREAMPLIFIER

In celebration of 45 years in the audio industry, Virginia, USA based Conrad-Johnson Design has announced the release of their new anniversary reference line-stage preamplifier, the Conrad-Johnson ART88.

The Conrad-Johnson ART88 will be available in a numbered, limited edition of 250 units.

CONRAD-JOHNSON ART88 REFERENCE PREAMPLIFIER

The ART88 is configured essentially as a dual-mono preamplifier, with the two channels sharing only a power transformer and the chassis. The ART88 adheres to the brand’s maxim that best results are obtained through the execution of simple circuits carefully executed with highest quality component parts.

INDEPENDENT POWER SUPPLIES

The circuit for each channel consists of a single triode gain stage utilising paralleled sections of a PCC88 twin-triode vacuum tube coupled to the output through a buffer stage incorporating paralleled sections of a second PCC88 for low output impedance. Each channel is provided with an independent DC power supply with a discrete voltage regulator.

HIGH QUALITY COMPONENTS

Conrad-Johnson says that the ART series of products are notable for the quality of parts, as well as attention to mechanical details. CJD Teflon capacitors and Vishay metal foil resistors are used throughout the audio circuit and for the regulated plate voltage power supply. I/O connectors are machined from oxygen free copper, then silver plated with a Rhodium flash. The level controls and audio circuits are shock mounted on independent daughter boards and the casework is executed in heavy gauge aluminium to minimize microphonics.
