Vinyl Calibration Gauge & Protractor

This acrylic gauge helps vinyl owners set cartridge overhang and alignment on any tonearm that accepts a half-inch mounted cartridge. The printed protractor and included magnifier give a clear visual reference so you can avoid overshoot distortion and keep tracking accurate.

Simple Alignment With Built-In Guide

The protractor carries a link to a setup guide printed directly on its surface, so the steps are always at hand. Acrylic construction keeps the tool rigid while you work, and the magnifier makes the fine scale easier to read. Manual measurement tolerance of up to three centimetres means you should verify critical dimensions with a ruler.

Covers Standard Speeds For Most Turntables

Markings for 33, 45 and 78 RPM let you check alignment across the common playback speeds. The gauge suits single-cartridge setups using an S-shaped arm and half-inch mount. It does not address tonearms with non-standard mounting patterns or users who need automated digital alignment.

  • Eliminates tracking errors and over-shoot distortion for better sound

Questions about this item

How do I confirm the protractor is aligned correctly after placing it on the platter?

The high-contrast printed scale and included magnifier let you verify the overhang setting visually; the guide printed on the protractor shows the correct alignment marks for an S-shaped arm with a 1/2" mounted cartridge.

What comes in the package and is anything else needed to start the setup?

The box contains one acrylic overshoot protractor measuring approx 19x4x2cm and one magnifier; no extra tools are required for the alignment procedure.

Which version of the gauge should I choose for a turntable that runs at 33, 45 and 78 RPM?

This single model works with all three speeds — 33, 45 and 78 RPM — so no separate version is needed.
