Have you considered using a white or yellow LED + resistor? Far more reliable. After the n'th bulb failure in the backlit display of an FM tuner, I replaced the light bulbs with LEDs in series and a resistor. End of problem.

It's a soundcraft 8000 that actually uses the audio +buss voltage (17 v) to power two 9 v lamps in series for each VU. There is aso a 100 ohm current control resistor in series to control turn on surge. So as you see 9v bulbs are perfect.

Perhaps there's something here:
"about 342 hits" for 9v grain of wheat lamp. (0.07 seconds)
I suggest to use two 18 volt lamps in parallel, then you don't need the control resistor. The 2102D is a
40 ma 18 volt wire terminal indicator lamp rated at 10000 hours, approx 7/32 " diameter with 5/8" leads.PolyTech Forum website is not affiliated with any of the manufacturers or service providers discussed here. All logos and trade names are the property of their respective owners.
