Do you want to experience the unique sound of a high-end tube amplifier, without the high-end cost.
Play your classic tunes just as the artists intended, on tube equipment.
RedRoo tube amplifier kits are easy to build and use top-quality components, and because you build them yourself they don't cost an arm and a leg.
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 analyzing complex circuitry.
If you feel you don't have the necessary experience you should either seek help from someone who does, or you should build a few simple electronics kits first. Easy steps!

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
