Hi Maurice,

I attach the manual for the horn and the signal-button. The last one describes the hole system. The system works with high-frequency modulation so you need at least 7215, a transformer and a horn.
The sound is not impressing. The noise is like a low beeper when a PC boots. Don't be disappointed.

This picture shows a 3050 with the horn installed:

Hi everyone - in the hope this thread about the old 60s marklin signal horn system is still alive, can anyone throw some light on the differences between the original 7213 horn, and the seemingly later 7214?
I can see the physical difference - the 7213 seems to be a sealed unit with an open horn end, whilst the 7214 is a small hearing aid type unit clipped into a sealed end plastic horn (I presume the hearing aid type unit was a bought in part for marklin ?)
Also any idea what the electronic component on the feed wire is? - looks like a capacitor, but what microfarad and volts? - the parts just say. 2/70 VALVO +27
Any help greatly appreciated
Thanks
Charles

Hi Markus

Thanks for that very quick reply and the information- duly noted, but it does beg the question as to why the later type horn has the earlier number?
