A site just visited as regards fitting decoders to older LGB electronics, refers to, in general, the necessity in fitting a rectifier and a capacitor between the track pickups and the LGB electronics to ensure 'pure' DC power to the board. Perhaps someone could enlighten me as to how one would wire up the capacitor in relation to the rectifier. I assume the capacitor is to smooth out the track power input.
Secondly, another site recommends using a relay to trigger analogue sound on older LGB factory sound locomotives that utilise an axle sensor to 'clock' the chuff sound. The site recommends a relay, via a function key on the decoder, to trigger the sound output. This leads me to believe that the decoder '+' and '-' are in fact 'pure' DC power and not DCC signals. Any thoughts.
