Hi
I'm the proud owner of a new-to-me Pfaff 1471 which appears to be functional in every respect except the low-bobbin-thread light.
Can anyone tell me whether the little lens in the bobbin cover is a lamp that should light, or a sensor? There's a matching lens buried behind the shuttle race. I'm assuming one's a light and the other's a sensor. The one at the front is in a transistor-type package; the one at the back may be too, but I haven't delved t hat far yet.
If anyone can shed any light (ugh) on the matter (including where, in the UK, I could order bits like these), I'd be grateful.
Regards John Midgley
