Norsk Radiofabrikk

Norsk Radiofabrikk — The Norwegian Radio Manufacturing Company

The company was founded in 1979 by Espen Evensberget, Paal Rasmussen, and myself. We aimed to develop and market our own designs, but most of our work involved modifying and refining the Two Channel Audio Amplifier.

The company ceased operations in 1981/82.

Some of the designs we developed can be found in the Technical Reference section

The company also put out its own press release, “Tre Faser i en Utvikling” (“Three Phases in a Development”), about the story of the Otala power amplifier including the NRF modifications, written in 1979 — that document hasn’t survived, or hasn’t been found again yet.
