Notes:
- Only one screw under the steam dome—then the housing can be lifted off from the top: electronics are under the boiler, motor is in the tender.
- Speaker housing removed, creating space for a capacitor. There is barely not enough room for 1000 µF, so only 470 µF was used.
- IR receiver glued to the tender coupling; the cable duct still has enough space for the IR cable. Feedthrough via a connector is not possible.
Conclusion:
- Very easy to open
- Simple conversion
- Soldering only required for the IR receiver.
