Experience the unique sound of a high-end tube amplifier, without the high-end cost.
Play your classic tunes just as the original artists intended - on tube equipment.
RedRoo tube amplifier kits are great sounding, very easy to build, and only use top-quality components.
They are the product of many years of professional design, engineering, and experimentation, and, because you build them yourself they are surprisingly affordable.
Save your precious time by choosing a solderless kit, or solder in all components yourself.
RedRoo tube amplifier kits will last you a lifetime, and there's nothing like saying "I built it myself".
Why Tubes?
Many musicians and audiophiles still prefer the sound of an old-fashioned thermionic tube (aka valve) amplifier. Tubes have a typically "warm" and "open" sound produced by the synergy of many factors that solid-state devices just cannot simulate. A RedRoo tube amplifier kit lets you experience your favourite recordings just as the original musicians and their sound engineers intended.
Is DIY for Me?
The difficulty level relates to the information in the table below. Levels 1 and 2 do not require any previous experience. Levels 3 and 4 require some knowledge of electronic components and their usage and reasonable soldering skills, or they have voltages over 50 Volts. Level 5 is for those who have experience handling very small electronic components and analysing complex circuitry.
If you feel you don't have the necessary experience you should either seek help from someone who does, or build a few simple electronics projects first. Easy steps!
The RedRoo solderless kit set is a great option as it saves a lot of time, and avoids having to solder all the individual components. If you can use a screwdriver you can build the solderless kit.

Tube Safety/Disclaimer/Copyright
Tube amplifiers are safe unless they are physically damaged, misused, poorly located, or are being worked on without taking appropriate safety precautions.
Electrical Safety - Hazardous Voltages
Tube equipment contains hazardous voltages, (several hundred volts, or more), and it can hold that high-voltage charge for a very long time after the power is switched off. If you are working on tube circuitry make sure it is switched off and the high-voltage power supply is fully discharged.
Burns or Fire Risk
Tubes operate very hot and can cause a nasty burn. They can also ignite materials that come into contact with them, such as flapping curtains, etc.
● Position Tube equipment well away from combustible materials. Leave at least 200 mm clearance on all sides and the top for adequate ventilation.
● Never leave a Tube amplifier switched on when unattended. Keep out of reach of small children
