Spectrum 128 +3 Sound Mod Resistor Kit. New

£1.10

Balance the audio levels of your classic Sinclair with this high-quality ZX Spectrum 128 +3 sound mod resistor kit.

Many later Spectrum models suffer from unbalanced audio or distorted output from the AY-3-8912 sound chip.

This kit provides the precise resistors needed to equalise the sound channels, ensuring your 128K music and effects sound exactly as the developers intended.

Each kit includes a handy ZX Spectrum 128 +3 sound mod resistor colour recognition chart to make identification and installation straightforward for hobbyists.

It is an essential upgrade for any +3 or 128K restoration project seeking superior acoustic performance and clarity.

Description

High-Quality Audio Resistor Kit for ZX Spectrum 128 +3 Sound Mod. New

The audio circuitry in the Sinclair ZX Spectrum 128K “Toastrack” and the later +2 and +3 models is often criticised for being poorly balanced. This can lead to the AY-3-8912 sound chip output being muffled, overly quiet, or distorted compared to the standard beeper sound.

Our sound mod resistor kit is a popular community-driven solution designed to correct these levels and provide a much cleaner, more professional audio output.

Key Features:

  • Improved Audio Clarity: Precisely calculated resistor values to balance the sound channels for a crisp, even output.
  • High-Quality Components: Features brand new, high-tolerance resistors for long-term reliability and performance.
  • Easy Identification: Includes a resistor colour recognition chart, making it easy for you to identify the correct values before soldering.
  • Versatile Application: Suitable for the original 128K “Toastrack” as well as the Amstrad-era +2 and +3 models.

What’s included:

  • Set of high-quality resistors required for the audio mod.
  • Resistor colour identification recognition guide.
