This section covers all the original Nytech products of the 1970s and 1980s.

Most parts except the slider controls and tuner IC’s are still available so we still offer a repair service for all of these wonderful amps as they were built to last!

When Nytech Audio moved to Mid Wales in the late 1980s they re-branded and became Ion Systems with a new range of Ion / Nexus amplifiers and the JC1 and JC1a loudspeaker.

The Nytech Audio Music lab is a new dedicated area for people more interested in the technical aspect of music making and reproduction.

It includes technical information, kits and DIY projects for electronics engineers (old and new), musicians, audio engineers and anyone else who loves to geek out on all the techie stuff!

Find out how stuff works by having a go at building it yourself!

EXO3 “State Change” electronic crossover module

The EXO3 is a 2/3 way electronic crossover which uses a single filter module for each crossover point by either adding or subtracting the output from the filter to the main amplifier stage. This results in a near perfect mirror of the frequencies (including phase) giving results that were only previously obtainable with digital signal processors.

This crossover is best suited to High End speaker designs which have reduced speaker anomalies by good cabinet design and choice of matched drive units.

A 2 way version can also be made by omitting the second filter element.

KPA2 Pure class A power amplifier driver board

The KPA2 is a driver board which can be used with appropriate output transistors (and heat sinks) to produce a pure Class A audio power amplifiers up to 50W RMS.

Because the builder has to add the output transistor arrangements themselves this is not a project recommended for the beginner without the skills to get it working!

CDP102 RIAA equalised phono stage

The CDP102 phono stage is intended to be used with a turntable with a magnetic cartridge. The design is based on the original Nytech / Ion phono stages which earned an enviable reputation for musical quality and enjoyment. Both moving magnet (MM) and moving coil (MC) versions are available.

These phono stages are fully discrete (using no IC’s in the signal path) and are an excellent introduction for anyone wishing to learn about phono stage design.

RPM1 Remote power module

The RPM1 is designed to switch on the AC power) (maximum current 10A) to an audio item (such as a power amplifier) in response to a contact closure to earth from a control device (such as a preamp).

Both 220V and 110 V versions are available and the module can be incorporated inside the equipment to be controlled or built into a custom box with appropriate mains connectors.

Please note this project involves wiring AC mains which can kill.

Only people experienced with safely wiring mains equipment and knowing the regulations in their own countries should attempt this project!
