the B250C1500 is a 1.5A 500V bridge rectifier
I would of thought a 1A bridge rectifier would be OK
or four 1N4007 diodes

So the guy stole it and put his own copyright message on it... I have my book shelves full of old books and magazines, even several years of Elektor (which I think is German from the beginning) but googling is faster than going through all of those.

Anyway, good detective work.
