SLW Class 25 DCC Sound & Super-cap kit

To upgrade the DC (analogue) model to full DCC sound specification with an enhanced stay-alive capability of approximately 3 seconds to avoid sound drop-outs, flickering lights and stalling on less than perfect trackwork. Comprises a MS450 PluX22e sound decoder pre-loaded with our bespoke Class 25 sound project, two SLW ‘Dumbo’ speakers with wired 2-way JST sockets (for direct fit to the PCB mounted plugs) and SC170 17,000uf compact super-capacitor (requires soldering).

Note: This kit is not compatible with any other model.
