Heljan O Gauge Large Prairie with Zimo MS440 21pin in Booster Board
Kit: MS440C; ADAMTC Booster; Ice28x18x08 speaker; 6x mini GoldCaps
Time for another Heljan Large Prairie in O gauge... this is still pre-MS950 (simply plug-in decoder for the L socket), but we
will use an MS sound decoder, an MS440C in an ADAMTC booster board, with speaker and stay-alive all in the boiler.
The body is totally removed as we want to add lamps to this model too.
Here we see the ADAMTC booster up front with the MS440C decoder plugged in and wired up.
YouChoos bi-colour working lamp on the back, with wired routed along the cab floor to the front.
Lamp on the front too.
Bird's nest of wired showing the position of the IceCube speaker, firebox PCB (original) and the 6 mini GoldCaps for stay-alive
- a 'neat'(ish) little package that just slides into the boiler when complete.
