thesteambuff Posted January 6, 2018 Share Posted January 6, 2018 Hi Has anyone upgraded the speaker on Hornby TTS steam locos,if so is it worth doing? Link to post Share on other sites More sharing options...
RAF96 Posted January 7, 2018 Share Posted January 7, 2018 Make sure you get replacements with correct 8-ohms rating. Some original round speakers have been flaky and people find that cube speakers work well and the smaller ones are easier to find space for.

RMweb Gold Chris Chewter Posted January 8, 2018 RMweb Gold Share Posted January 8, 2018 One of the problems I faced when experimenting with TTS, is the speaker is absolutely huge in comparison with other sound chips. I fitted the A1 tornado chip to an early Bachmann model, but found that trying to fit the enormous speaker in was a real pain. It wouldn't even fit in the tender! In the end I swapped the speaker to a Zimo sugar cube, which seems to have worked, and allowed me to fit the speaker in the smoke box. I'll try to get a video of the loco later and post it up for reference. Link to post Share on other sites More sharing options...
RMweb Premium Chamby Posted January 9, 2018 RMweb Premium Share Posted January 9, 2018 I have replaced the speaker on a TTS sound fitted Class 40. There’s loads of room inside for a good sized speaker, I used a 28x40mm speaker to good effect. It gives a sound that is both crisper and richer than the original. But as mentioned above, do be careful to get the impedance right. Link to post Share on other sites More sharing options...
thesteambuff Posted January 9, 2018 Author Share Posted January 9, 2018 Yes i have a class 40 as well terrible sound,i will upgrade. Link to post Share on other sites More sharing options...
Andy_Richards Posted January 14, 2018 Share Posted January 14, 2018 I have replace the speaker on a Vitrains class 37 and 47, i used a bass reflex speaker which greatly improved the sound quality. The only watch out as stated above make sure the new speaker is the correct 8-ohms rating Regards Andy Link to post Share on other sites More sharing options...

Andy_Richards Posted January 21, 2018 Share Posted January 21, 2018 Would be louder if it was 4 ohms. Charlie Can you use a 4 ohms speaker instead of 8 ohms speaker if the sound chip is rated at 8 ohms? Or do you need to use 2 x 4 ohms? Thanks Andy Link to post Share on other sites More sharing options...
Chrisr40 Posted January 27, 2018 Share Posted January 27, 2018 Afternoon all Quick question. I have been setting up my class 31 chip with a powercab and ever since I changed the powercab to access functions over f12 the horn sounds after every other sound I select has played. Any ideas folks ? Many thanks Link to post Share on other sites More sharing options...
Dunmar Posted January 28, 2018 Share Posted January 28, 2018 Hi, Thought I might experiment with a couple of TTS decoders so got myself 1-CL47 and 2-CL37 and fitted the 20x40 speakers from Richard Croft which vastly improved the sound quality. After fitting the decoder in a Vi-trains 47 I had to alter CVs 151/152 as per Hornby Tech Services it seem to improve the 'stutter' effect. However, I fitted the two Vi-trains 37s with the decoders of which only one seemed to run okay whilst the other suffers from a bad stutter and the lights don't work in one direction. Having altered CVs again and the EMF,it doesn't seem to help. I have now come to the conclusion that the decoder is at fault as when fitted with a non-sound decoder the loco runs normal and lights work in both directions. Any ideas as what to do next before I return to retailer. Regards, Bill. Link to post Share on other sites More sharing options...
RAF96 Posted January 29, 2018 Share Posted January 29, 2018 Bill It could be your TTS decoder is one of those that needs its firmware reprogrammed by Hornby and it has slipped through the net. Call HCC to arrange to get it done. Chris Is your track complete loops with/without a bus. If so you may want to try gapping the track in each loop. You could try fitting RC snubbers to the track or bus to eliminate any spurious signals which may be causing your extra toots. There is plenty of advice not to make your bus into a loop but trackage is usually always laid as a continous loop. Rob Link to post Share on other sites More sharing options...
Chrisr40 Posted January 29, 2018 Share Posted January 29, 2018 Hi bill thanks for the suggestion. At the moment it's just a single length of track. Chris Link to post Share on other sites More sharing options...

S&DWatty Posted January 29, 2018 Share Posted January 29, 2018 Ive just sent a TTS decoder back following loss of drive and intermittent sounds. Hopefully, its a firmware issue too and Hornby will fix it. dave Link to post Share on other sites More sharing options...
RMweb Premium Boco_D1 Posted January 29, 2018 RMweb Premium Share Posted January 29, 2018 (edited) I’m glad you mentioned this issue I ran my 37 around a bit of test track yesterday and put the stutter down to dirty track. Trying again today mine appears to have the same symptoms as others mentioned on here so I too shall be contacting Hornby.

RMweb Gold chriswright03 Posted January 29, 2018 RMweb Gold Share Posted January 29, 2018 Have you changed the cv values as per the suggestions by Hornby first to see it that cures the stutter? Link to post Share on other sites More sharing options...
pauliebanger Posted January 29, 2018 Share Posted January 29, 2018 Who is paying the postage for all these duff decoders going back and forth? Paul Link to post Share on other sites More sharing options...
RMweb Premium Boco_D1 Posted January 29, 2018 RMweb Premium Share Posted January 29, 2018 I phoned Hornby and changed cv’s as suggested but to no avail, I have four tts decoders, one is in the railroad fitted 31, and the others are the solo 37, 47 and 60 chips. Only the 60 goes at slow speed the others all share the same slow running stutter issue. I will be returning the offending chips for reprogramming. As for postage I’m paying to return but I assume Hornby will pay to send back. 1 Link to post Share on other sites More sharing options...
RMweb Gold chriswright03 Posted January 29, 2018 RMweb Gold Share Posted January 29, 2018 Who is paying the postage for all these duff decoders going back and forth? Paul Have a guess Paul! I suspect owner pays to return it then Hornby to send it back. One or two have done this already so they will be able to say for certain. I understand what you are getting at though. Under warranty terms they are being fixed but the owner should not have to pay for decoders not doing what they should. Link to post Share on other sites More sharing options...

Dunmar Posted January 30, 2018 Share Posted January 30, 2018 Hi, Having received my replacement CL37 TTS decoder from Hornby I set about fitting it to Bachmann model. I got the the same 'stutter' and set about changing CV151 to 255 and CV152 to 1. but it doesn't like the Bachmann 37. The Vi trains 37 fairs much better and respond to the change. Are there any other CV's I should be looking to change or considering the previous posts regarding faulty decoders should I treat mine the same as it still stutters??? Bill.

paftrain Posted January 30, 2018 Share Posted January 30, 2018 Who is paying the postage for all these duff decoders going back and forth? Paul I sent a Class 31 back to Hornby for a reblow and after returning it to me promptly I then received a cheque to cover my cost of postage to them.Excellent service! Thank you Hornby.

Dunmar Posted January 30, 2018 Share Posted January 30, 2018 I spent a good hour this evening trying to get mine running right, I got it better than it was but it’s not perfect. I switched to the alternative alithogram, I think it was cv150 to 1 to change that, then I changed 153 to 255 and 154 to 1. It sets off slightly too quick in speed step 1 but runs fairly smoothly, especially in speed step 2 onwards. Still happy with it for the money, I’m impressed how customisable it is through the CV settings. Richard Hi Richard,Thanks for the info, I've spent most of this morning trying to get this Bachmann 37 to run smoothly but with little success. Both my Vitrains 37 and 47 seem ok but just might try your option on them to see if there is any difference. Oh! and I will be getting in touch for another 20 x 40 speaker☺!

Under warranty terms they are being fixed but the owner should not have to pay for decoders not doing what they should. I had a blown TTS decoder in my A4 less than 1 year old. Hornby asked me to return the loco which I did. £3.90 postage to post it to them. When I received it back something was catching and jamming the valve gear so back it went, another £3.90. Received it back after repair and still jamming and catching. Another £3.90 to send it back. Finally received it back running OK. They refunded all my postage costs under their T&C so you should get postage refund if not send them an email. Wiggy.
