Hi Alf
As the bulb is measuring about 40 Ohm it should be OK.
Check 1 R 30 (15 OHM) and all tracing connections.
About Transistors which are measuring off board in a good state….
If I pull one of these little BC5XX Transistors out I always put a new one in, cost only 5 to 20 cent and you’re shure that the new one will work.
Had already a lot of them measuring good, but a HFE about 20 or 100, too low in that case.
Hope it will help a little bit.
Kind regards
Christian
