The Model 82 and 82 Classic are a single-ended Class A vacuum tube preamplifier designed for providing the characteristic harmonic richness of the triode. The circuit topology creates a vintage triode sound with warm qualities of the 2nd harmonic that can add this character to a solid state or tube amplifier.

The 12AU7 (ECC82) is an excellent tube for both its sonic characteristics as well its wide availability, comparatively low cost, and current production status. The Model 82 is a great choice for those who would like to experiment with tube rolling as both new production and vintage models are available.

The Model 82 platform allows for full customization including (but not limited to) enclosure type and color, wood side panels, front panel power switch type, high/low gain switches, source selection switches, level control type, IEC inlet for use with 3-prong AC power cables, a ground lift switch, Single-Ended inputs, Single-Ended outputs, Single-Ended/Balanced output selection switches, and balanced XLR outputs.

The 82 Classic is a single vacuum tube design ideal a more traditional, vacuum tube colored sonic character. The Model 82 is a dual tube version that takes linear performance to the next level and delivers a more modern presentation of the music.

A custom designed linear regulated B+ supply as well as a linear regulated heater supply provide exceptionally low noise and stable performance.
