For most of us a high-power valve amplifier is unaffordable. This kit changes that, so that now everybody can enjoy that sublime "valve sound". The sound of valves has never been 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 most vulnerable point of a valve amplifier are the output transformers; that's the reason 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.
