The story behind the sound.
In 1972 Dr. Otala and Mr. Lohstro fi nished their work in
analysing transistor amplifi ers 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 amplifi er.
This product was the fi rst commercial transistor amplifi er
to use this new design approach, and the amplifi er was
immediately recognised as dramatically more musical and
dynamic sounding than any other transistor amplifi er. The
same design philosophy has been constantly updated by
additional research and development. This philosophy forms
the basis of the new ABRAHAMSEN© design.
After the 25 watt amplifi er had established a new standard
for transistor amplifi ers, research was undertaken to fi nd
ways to make the amplifi er even better, and to extend its
highly musical sound quality to more powerful amplifi er
design.
