Velleman Project Kits Range

For most of us, a high power valve audio amplifier was an unaffordable luxury. The Velleman K4040 Chrome Stereo Valve Amplifier SELF-ASSEMBLY electronic kit changes that, so now everybody can enjoy that sublime "valve sound". For many audiophiles, the rich, warm sound created by vacuum tube valves cannot be surpassed, either by transistors or FETs.

In the development process, special attention was paid to the housing so that the expensive valves are displayed in a visually attractive manner. The chrome version features a reflective cover plate to further enhance the visual effect.

The most vulnerable parts in a valve amplifier are the output transformers; that's why we use ultra-linear and overrated output transformers (toroidal) to guarantee a rich bass response.

To extend the life of the precious valves, the amplifier has a switch-on delay so the high voltage is only switched on once the valves have warmed up.

As Velleman UK Main Dealer we can provide full support for your purchase if required including replacement parts if you should need them.
