The story behind the sound.
In 1972 Dr. Otala and Mr. Lohstro finished their work in
analysing transistor amplifiers to determine what actually
created the ”transistor sound” in general transistorized
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 and
dynamic sounding than any other transistor amplifier. The
same design philosophy has been constantly updated by
additional research and development. This philosophy forms
the basis of the new

After the 25 watt amplifier had established a new standard
for transistor amplifiers, research was undertaken to find
ways to make the amplifier even better, and to extend its
highly musical sound quality to more powerful amplifier
design.
