VALVES
EASY
BIAS ADJUSTMENT
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 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.
