For most of us a high power valve amplifier is unaffordable. The K4040B Stereo Valve Amplifier (Black version) SELF-ASSEMBLY electronic kit changes that, so that now everybody can enjoy that sublime "valve sound". The sound of valves cannot be surpassed, neither by transistors nor FETs.
In the development process, special attention was given to the housing so that the expensive valves are displayed in a visually attractive manner. The Black version features a subtle black valve cover plate with rear mirrors.
The most vulnerable point of 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 that the high voltage is switched on when the valves are warmed up.
