Manufactured in the 1992-1995 period, the NAD 106 is still a great-sounding pre-amplifier today.
Despite the capacitors showing no sign of fatigue, they were 40 years old, so a recap-job was welcome.
All power-supply electrolytics capacitors have been changed for 105° long-life versions. While the box was open I changed all capacitors in serie of the signal in the output section.
This pre-amplifier will soon feed a tube amplifier, and serves as phono section for a vintage Pioneer turntable that awaits service.
