URVAL – TYPE “E”

​

Overview

The Urval Type “E” is a machine built with quiet confidence.

It doesn’t shout.
It doesn’t over-decorate.
It simply delivers solid, dependable high-frequency output in a form that was clearly intended for serious, repeat use.

This is British engineering doing what it does best — understated, deliberate, and correct.

Engineering & Layout

The Type “E” layout is clean and purposeful:

  • Wide, tactile dials for smooth adjustment

  • Clearly marked dual-voltage support

  • Internal spacing designed for electrical stability

Everything here prioritises control over spectacle.
The operator is meant to work with the machine, not fight it.

Output Character

Urval units are known for an output that feels:

  • Even

  • Grounded

  • Predictable across the range

This makes the Type “E” especially suited to:

  • Extended sessions

  • Methodical electrode work

  • Precise modulation rather than brute force

It’s a machine you settle into, not one that demands constant correction.

Electrode Set

The supplied electrodes reflect practical intent rather than novelty:

  • Multi-prong comb electrode

  • Curved surface electrodes

  • Spiral / coil-based glass forms

  • Straight directional probes

Each electrode is designed to alter field geometry, not just appearance — a hallmark of thoughtful design.

Handle & Cabling

The brown bakelite handpiece and cloth-braided cable are not just aesthetic:

  • Excellent grip and balance

  • Reduced handling fatigue

  • Durable insulation for long-term use

This is the sort of handle that feels right the moment you pick it up.

Build Quality

From the case to the panel to the fittings, the Type “E” carries the unmistakable signature of Made in England craftsmanship.

  • Robust construction

  • Conservative electrical design

  • Materials chosen for longevity, not cost

This is a machine meant to last decades — and many have.

Restoration Perspective

Urval Type “E” units respond best to light, respectful restoration:

  • Contact cleaning

  • Dial calibration

  • Cable and insulation checks

  • Capacitors changed

They do not benefit from modification or “modernisation.”
Their strength is in remaining exactly what they are.

Why the Urval Type “E” Matters

This model represents a period when high-frequency apparatus was treated as:

  • A professional instrument

  • A precision tool

  • A long-term investment

It sits comfortably alongside other serious British units of the era and holds its own without needing exaggeration.

Final Word

The Urval – Type “E” is calm, capable, and quietly authoritative.

No theatrics.
No gimmicks.

Just proper high-frequency engineering done right.
