Control “B” Evolution

Reference-Class Vacuum Tube Preamplifier

High-end preamplifier

This new preamplifier perpetuates all the values which have established the reputation of the Control “B,” adding some refinements in relation to the permanent search for more precise, more stable, more musical components.

Tube-Based Architecture

Entire signal path implemented with vacuum tubes (triodes/double triodes) for characteristic tube sound quality.

Gain & Control

Adjustable gain settings at the line inputs to match a wide range of source sensitivities.

Phono Stage

Integrated RIAA-equalized phono input supporting both MM (moving magnet) and MC (moving coil) cartridges.

Signal Inputs & Outputs

Provides multiple stereo line-level inputs with source selection, includes a monitoring (tape) loop for recording and playback monitoring.

Build Quality & Chassis

Rigid steel/aluminum chassis with thick front panel for mechanical stability and shielding.

Power Supply Upgrade Available

Standard power supply or optional Dual Regulated Power Supply (DRPS) for improved noise performance and voltage stability.
