Audiophile Quality Stereo Tube Amplifier

For most of us a high power tube amplifier is unaffordable. This kit changes that, so that now everybody can enjoy that sublime "tube sound". The sound of tubes has never been surpassed by transistors or by FETs. In the course of developing this amplifier, special attention was given to the housing so that the expensive tubes are on display in a way that is very pleasing to the eye. The weakest point of an tube amplifier are the output transformers; that's the reason why we use ultra-linear and over-rated output transformers (toroidal) to guarantee a rich bass response. To extend the life of the precious valves, the amplifier is provided with a switch on delay, so that the high voltage is switched on when the tubes are warmed up.
