Hornby OO LNER B1 (21pin version)

Kit: MS440C; YC28R round speaker; 1000uF cap

Simple fit of MS440 and 28mm round speaker into this Hornby B1, just using the standard 1000uF/16V capacitor that comes with the decoder for stay-alive - wrap in Kapton and place just behind the socket. Speaker wires are connected to 'S' pads provided on the model's PCB.

Note that the decoder plugs in upside down compared to most 21pin models!
