Audio Hungary QUALITON C200 Preamplifier

Audio Hungary QUALITON C200 Vacuum Tube Preamplifier

The Audio Hungary QUALITON C200 Preamplifier is a high-end vacuum tube stereo preamplifier combining eight ECC83/12AX7 valves, a dedicated moving magnet phono stage, an integrated headphone amplifier and extensive analogue connectivity.

Part of the acclaimed Qualiton Classic Series, the C200 brings together traditional Hungarian vacuum tube engineering and modern convenience, making it an exceptionally versatile control centre for a sophisticated high-fidelity audio system.

Featuring original Tungsram ECC83 vacuum tubes in its factory configuration, a custom-designed power transformer, precision relay-controlled input switching and a premium Japanese ALPS motorised volume control, the C200 has been developed to deliver refined analogue performance with excellent operational flexibility.

Available from Chameleon Audio, the QUALITON C200 is an attractive solution for audiophiles seeking a dedicated tube preamplifier with integrated MM phono and headphone functionality.

A Complete High-End Vacuum Tube Preamplifier

The QUALITON C200 is designed for demanding music enthusiasts who wish to combine multiple analogue sources with a high-quality external power amplifier.

Its seven analogue inputs accommodate compatible digital-to-analogue converters, network streamers, CD players and turntables equipped with moving magnet cartridges.

Separate line-level outputs, a balanced stereo output, a dedicated subwoofer output and a headphone connection further increase the flexibility of the system.

The manufacturer’s design philosophy focuses on maintaining a balanced, natural sound character while providing carefully controlled electrical performance.

Eight Tungsram ECC83 Vacuum Tubes

Selected NOS Tungsram ECC83 Valves

The QUALITON C200 uses eight ECC83/12AX7 vacuum tubes, with Audio Hungary highlighting the use of selected Tungsram ECC83 valves.

These Hungarian-made tubes are an important part of the amplifier’s analogue circuit architecture.

Audio Hungary describes its stock of New Old Stock Tungsram valves as a distinctive element of the C200 design.

The tubes are selected for low noise, symmetry and distortion performance, contributing to the consistency of the preamplifier’s operation.

Tube availability and the exact supplied brand should be confirmed for the current production unit.

Custom-Designed Toroidal Power Transformer

In-House Transformer Engineering

The QUALITON C200 incorporates a custom-designed power transformer manufactured using Audio Hungary’s specialist transformer expertise.

The transformer employs a high-permeability toroidal magnetic core and carefully designed windings intended to provide stable electrical operating conditions.

Double electromagnetic shielding helps reduce interference between the power supply and sensitive low-level audio circuits.

The transformer assembly is also potted with epoxy compound to minimise mechanical vibration and associated noise.

Careful power supply engineering is particularly important in a vacuum tube preamplifier that handles low-amplitude analogue signals.

Integrated High-End MM Phono Preamplifier

Vacuum Tube MM Phono Stage for Vinyl Playback

One of the C200’s most significant features is its integrated moving magnet phono preamplifier.

Audio Hungary developed this circuit from its long-standing research into vacuum tube phono amplification.

The MM phono stage uses vacuum tubes and passive components within the equalisation and amplification architecture.

With a published phono gain of +57dB and a nominal input impedance of 47kΩ, the circuit is designed for suitable moving magnet cartridges.

Owners of low-output moving coil cartridges may use a correctly matched external MC step-up transformer before the MM phono input.

This provides a convenient option for integrating a serious analogue front end without requiring a completely separate phono preamplifier.

Integrated Headphone Amplifier

Dedicated Headphone Listening

The QUALITON C200 includes an integrated headphone amplifier for personal listening.

The headphone section is engineered to work alongside the preamplifier circuitry while maintaining the manufacturer’s intended sonic character.

It provides a practical solution for audiophiles who want to enjoy their music collection through compatible headphones without adding another dedicated component.

Headphone suitability depends on the electrical characteristics of the connected model, including impedance and sensitivity.

Seven Analogue Inputs for Flexible System Integration

The QUALITON C200 offers a comprehensive selection of analogue inputs designed for modern and traditional audio sources.

• 4 unbalanced stereo line inputs
• 2 balanced stereo line inputs
• 1 dedicated MM phono input

With four RCA line connections and two balanced line inputs, the C200 provides considerable flexibility when integrating DACs, music servers, CD players and other analogue sources.

The dedicated MM phono input allows a compatible turntable to be included within the same system.

Precision Relay-Controlled Input Selection

Japanese Relay Switching

The C200 uses precision miniature Japanese relays for selecting between its seven analogue inputs.

The manufacturer’s chosen components incorporate low-resistance contacts with gold-overlaid silver contact surfaces.

This relay-based architecture is designed to provide reliable source selection while maintaining carefully controlled electrical connections within the signal path.

Front-panel status LEDs indicate the active input selection.

Japanese ALPS Motorised Volume Control

Smooth and Accurate Volume Adjustment

The QUALITON C200 employs a high-quality Japanese ALPS motorised volume potentiometer.

ALPS volume controls are widely used in specialist audio equipment for their mechanical precision, consistent operation and reliable construction.

The motorised arrangement allows the volume to be adjusted directly from the front panel or remotely from the listening position.

This component is part of Qualiton’s emphasis on practical, high-quality analogue control.

Four-Function Remote Control

Convenient Remote Operation

The included remote control features a refined matte black finish and provides the essential operating functions.

Volume Up and Volume Down allow convenient listening-level adjustment.

A dedicated Mute function provides immediate silencing, while the Power On / Standby button offers control over operating status.

The remote makes the C200 easy to use as the central control component of a high-end stereo system.

Premium Electronic Components and Construction

Carefully Selected Internal Components

The QUALITON C200 uses selected components throughout its vacuum tube and power supply circuits.

• Tested and selected ECC83/12AX7 vacuum tubes
• Gold-plated ceramic tube sockets
• Gold-plated audio terminals
• Film capacitors in the audio circuitry
• Selected ceramic composition resistors
• Long-life, high-temperature power supply capacitors
• Integrated mains interference filtering

These components are chosen as part of Audio Hungary’s engineering approach to dependable, high-quality analogue performance.

Understated Qualiton Classic Series Design

The C200 follows Qualiton’s restrained industrial design philosophy.

Rather than relying on excessive ornamentation, the amplifier combines a clean front-panel layout with carefully executed mechanical details and intuitive operating controls.

With a substantial chassis measuring 43cm wide, 40cm deep and 16cm high, the preamplifier is designed to integrate naturally into a serious audio installation.

Balanced and Unbalanced Outputs

The C200 provides multiple output connections for flexible system design.

• Unbalanced LINE output
• Unbalanced SUB output
• Balanced stereo line output
• Headphone output

These output options allow the preamplifier to be connected to suitable stereo power amplifiers and compatible subwoofer systems.
