Dapol O Gauge LSWR B4

Dapol O Gauge B4 with Zimo MS Sound

Kit: MS440D/C; IceCube28X18X08; SuperCap6800uF

Dapol's little B4 recreated for O gauge here, very heavy and Dapol's great slide-out boiler PCB for fitting DCC and sound to, so a very simple upgrade.

Example 1 Example 1

The slide-out PCB has a pair of resonator boxes for 15x11mm StickyGasket speakers, so that's an easy approach, but we opt to fit the larger dual IceCube28X18X08, which is almost as easy - just the 2 wires to solder onto one pair of the speakaer pads of PCB.

Example 1 Example 1

On the socket-side, we plug in our MS440 21pin sound decoder, and BlackTack a 6800uF SuperCap for stay-alive - nice neat fit. Probably a good idea to cover the SuperCap with Kapton tape for added insulation, since the case of the SuperCap is joined to the Ground leg.

Example 1

With that done, the PCB slides back into the boiler, and job done!
