Hi Christian,
In Germany, you can get it from Segor: http://www.segor.de/suche.shtml?foto=0&Q=LNBP16&M=1 So it might be a good idea to ask/search on vdr-portal or offer the spare ones there.
Ah ok :-) so I'll see what i can do :-)
If VDR is tuned to a transponder with vertical polarization, you should see 13V supply on the connector. With horizontal polarization, it should be 18V.
Ok my Voltage was 0V when it should be 13V and a sawtooth like voltage aroud 14V-19V
Thanks Patrick
