A nostalgic stem for adjusting the volume
We used the flagship series “pro-audio series” of the famous ALPS volume potentiometer in Japan. The dust cover and grounding connection were ordered according to the specifications of the Pocket HIFI player. The rate of the volume error was lower than 5% in average after 1,000 hours’ text. The volume error rates of the HIFI player was15% lower than the ALPS official data.
