Ahhh, thanks Ray. I still need to replace several bulbs of my NOVA3 console.
Somebody knows of a source for 28V 40 mA “grain” bulbs with wires? I could use some 10 … and 20 as spare 😊 BTW, I read somewhere that the bulb to LED replacement is not as straight-forward as you may think. The small continuous current through the bulbs (to prevent thermal shock) is enough to make LEDs appear continuous on! - Henk.

The S/130 was DG's first LED-based front panel and was much-appreciated by Field Service. More followup off-list...
