Today I received copies of the schematic and parts layout for
the Nova 3 panel from Peter Simpson. I believe Perer also
sent a copy to bitsavers. Thanks Peter!!
The correct part number for the bulbs is 014-02, which
makes it a CM2176 equivalent. The CM2176 has only a 1000
hour

I was looking at this sale on ebay from Vince's part number. Also it is a US
shipping source, so may not save Henk anything. But it is the lowest cost I
found around.

Mouser has 950 CM2185 bulbs in stock, which should work nicely.

The Netherlands version of the site has the same quantity. Maybe

Thanks for the link... I went up the tree and saw the pics of that ADDS Envoy
terminal. I'm exceedingly green with envy. Congrats on an awesome piece of kit!

I'm not a big fan of the surgery involved in LED conversion, though I
understand why folks do it. Particularly if they, like Emil, have

DG generally used 28V, 0.040 Ma (nominal), fragile wire-lead
incandescent bulbs for the Nova/SuperNova/Nova2/Nova3 front panels as
well as the early Eclipses. The S/130 was DG's first LED-based front
panel and was much-appreciated by Field Service.
More followup off-list...

Not yet. One listmember expressed interest but nothing firm. Two racks of
DGblue just waiting for someone to cart them off ;) One is an S/200 and it uses
bulbs. My S/130 uses LEDS I seem to recall, but
