ES1 Sound Fitting Guide
The ES1 is a nice model to fit sound to, start by removing the contact shoes, you can just prise them off gently using a prising tool or screwdriver, this gives easier access to the screws.
The model uses a next18 decoder which fits in easily.
There is a built in speaker but we recommend swapping the speaker driver for one of our 15x11 speakers, which is much louder and higher quality. No soldering is required.
The installation and a video of the loco running with our sound is covered here
