Hornby Princess Sound Fitting
Here's our method of easily fitting high quality sound to the Hornby Princess using a 35x24x3 bass enhanced speaker. Start by removing the 2 screws at the front of the tender.
Start by cutting off the thin bracket on the speaker with a dremmel or razor saw.
Fit the speaker under the weight, one of the weight screws is under the 8 pin socket.
The decoder needs to be placed towards the back of the tender to make sure it doesn't get in the way of the coal bunker.
