How can I fix the lamps for the display
on my NAD amplifier
The original incandescent bulb(s) may be socketed, or soldered to a printed circuit board. A visual inspection of the bulb(s) is the best way to determine a replacement. If an LED solution is appropriate, I recommend using a few Cree 5mm clear white LEDs with 110 deg viewing angle and a resistor. These wide angle LEDs are designed for outdoor display lighting and help even the light intensity across a flat surface. (ex. Cree C535A-WJN) The Model 120 has an linear scale tuner with a blue film so white LEDs should look fine.
