Digitization of BB 660128 from Piko - part 1

 

This post largely follows a previous one and is therefore very similar - link here.

Analog run

Here's a short video on the engine running analog - very smooth:

Installation of the decoder

It is very easy to open the engine; refer to this video. Otherwise, the notice explains it clearly:

I used Piko 56427 for the sound decoder:

The dummy decoder is easy to locate and remove:

Then, the new one is installed:

The manual is also very clear:

Installation of the speaker

The space for the speaker is occupied by a weight. It is removed by unscrewing two tiny screws: one is holding the weight and the other holds the PCB: 

In the spare parts, we need two rectangular plastic components that will hold the speaker in place, and will like serve as a soundbox. As you might have seen on the previous picture, the speaker I had was too large and I had to order another one. I could not immediately find a Piko speaker, so I ordered something similar: 

• Train Control Systems N 1699 - link

According to the manual, the wires to the speaker need to be soldered directly on the PCB:

It can then be put into the soundbox and located back into the engine:

All of those steps are explained clearly in the notice:

ECoS configuration

Digital run

Here's a short video on the engine running digital - smooth, but not happy with the sound:

I'm waiting for a genuine Piko 56330 speaker ....
