ANDRÉ / C.A. HIGH-FREQUENCY UNIT – MOD. 004

​

Overview

This André / C.A. Mod. 004 represents a fascinating French transitional design, bridging classic violet ray architecture with the cleaner, more regulated aesthetic of the 1970s.

It’s compact, deliberate, and unapologetically functional — built at a time when high-frequency technology was being refined rather than reinvented.

Design Character

Unlike ornate early clinical units, this system leans into:

  • Minimalist panel layout

  • Clear visual feedback

  • Direct, user-friendly operation

The typography, indicator lamp, and control geometry are unmistakably 1970s French — restrained, confident, and practical.

Output & Behaviour

The output character is:

  • Clean and well-regulated

  • Easy to control across the full intensity range

  • Stable at both low and mid settings

  • Responsive to electrode changes

It delivers a measured electrical field, avoiding the harshness sometimes found in earlier over-driven designs.

Electrode Set

The included electrode selection covers a versatile working range:

  • Mushroom electrode

  • Curved anatomical electrode

  • Point and probe styles

  • Clear glass for visible discharge

  • Coloured glass electrode for altered plasma characteristics

The coloured electrode adds a distinct visual and energetic contrast, making this set especially appealing to users who appreciate output nuance.

Electrical Architecture

Internally, the unit follows classic high-frequency principles:

  • High voltage

  • Extremely low current

  • Rapid oscillation

  • Dielectric glass coupling

The visible glow remains a byproduct — the function lies in controlled field interaction.

Restoration

The unit has been fully electrically restored, including replacement of all capacitors as standard, with original circuit behaviour preserved and output tested under load.

It operates exactly as intended — stable, predictable, and confident.

Case & Presentation

The original case presents cleanly, with:

  • Secure electrode mounting

  • Integrated cable management

  • Compact, transportable format

It feels purposeful rather than decorative — a working instrument first.

Final Word

This André / C.A. Mod. 004 is:

  • Distinctly French

  • Historically interesting

  • Fully restored

  • Easy to live with and use

A sharp, well-designed high-frequency unit from a period where refinement mattered — and one that fits perfectly within a serious violet ray collection âš¡
