Hmm, I'd not be too sure about that. I believe the correct bulbs are 12V
or perhaps 14V, T1-3/4 bi-pin, 0.04A (that's 40mA). I've seen 14V 80mA
bulbs in a few places, but I'm not sure if they would be "safe" in the
panel - they'd draw twice the current and I'm not sure if the driving
transistors are rated for that. Anyone know? (I have a panel, but not a
print set).
If it's any help, I found some of the proper bulbs for my -8/E recently,
and they are marked "OSHINO-1 12-09169" or "PL10161 1209169". I think
the 12-09169 may be the DEC part number. On test, they draw between 30mA
and 35mA at 12V, and between about 35mA and 40mA at 14V.
The ones I've found in the Farnell catalogue (cat no 329-216) seem to be
made by EBT Technologies, part no 7382, and they're 14V, 80mA, 1.12W, 3.8
lumens, nominal life 15000 hours, priced around 50p (about 72 cents)
depending on quantity. I found the same bulbs slightly cheaper in the CPC
catalogue, for those of us in the UK.
