In 1972 Dr. Otala and Dr. Lohstroh
finished their work in analysing transistor amplifiers to
determine what actully created the "transistor sound" in
general transistorised designs. The results of their
innovative design work were incorporated in the legendary 25
watt amplifier. This product was the first commercial
transistor amplifier to use this new design approach, and
the amplifier was immediately recognised as dramatically
more musical sounding than any other transistor amplifier.
The same design philosophy, has been constantly updated by
additional research and development.
believe that uncompromising quality is not an option -
it's an obligation.
