NAD 502 Display bulbs?

richardmoon · 9th February 2009, 01:35 PM

Hi,does anyone know what bulbs to use for the backlit display on a nad 502.I tried some 14v,37ma bulbs as advised elsewhere but both internal fused blew.I did switch it on with the front panel disconected,not sure if this makes a difference.Thanks

Guess what I did? I replaced my old 701 back light bulbs with white super bright LED

COOL.

Hi mhifi508. What LED did you use? Maybe someone else can suggest one? Regards Bjørn.

until now I use leaded 6V bulbs as showed about
Bulbs - 6v | Mollys House Miniatures
and add a resistor between 10 ohms and 200 ohms - independend of the current from the bulb and the wanted brightness (as dark as possible, just so, that you can still read the display).

Are there any experience with the new generation of bright LED's?
