In this video I show how easy it is to fit a TTS sound decoder into a Hornby Class 08 shunter - and by upgrading the speaker getting a great sound from what is a cheap and basic sound decoder. Speaker: www.roads-and-rails.co.uk/col...
The speakers that come with TTS chips are well known for being quite poor. I did a quick test and this one is no different. It simply wasnt able to produce the range of sound it should. The new speaker gives a wide range of tone.
