BritInVanCA Posted April 4 Share Posted April 4 My prefitted speaker my TT120 A3 has blown. I want to fit the new one in the same space. Based on the picture below is it just glued in? How do you remove it? Link to comment Share on other sites More sharing options...
CaNNoN_1981 Posted April 4 Share Posted April 4 When was the loco purchased? speakers in TT loco's shouldn't be blowing so soon. I'd sent it back to Hornby for a replacement. Link to comment Share on other sites More sharing options...
ateshci Posted April 4 Share Posted April 4 Use a screwdriver and gently pry it out. Link to comment Share on other sites More sharing options...

I have to agree though speakers shouldn't blow and if I remember from my audio days, if they go short circuit they take out the audio stage of the driver. 1 Link to comment Share on other sites More sharing options...

Yes I’m overseas as my user name implies so I tend to limit returns to the things I can’t fix myself. I wasn’t going to go into a long explanation but I had the HM7000 decoder fail in this locomotive. After months of normal operation the locomotive started causing an overload fault whenever it was on the track. Even when stationary. When I removed the decoder and ran it on DC it was fine. I returned the decoder to Hornby and they replaced it but it seems the issue also took out the speaker. Link to comment Share on other sites More sharing options...

Just be aware the built in speaker is connected into circuit via spring contacts whereas the aftermarket decoder speaker is plug wired. With the original speaker removed and the 'box' speaker replacing it make sure you don't short anything out by inadvertent contact with the loco circuit board. 1 Link to comment Share on other sites More sharing options...
