Steve Smith Omg 😮🤦🏻‍♂️

@@cheekytek i look forward to you showing off your new 08 on your next upload :-)

Glad it’s of help. Dead easy 👍

Yes, there is more room than I’ve used

the 25v 75uf capacitor supplied, according to Digitrains, keeps the chip alive for a fraction of a second, which apparently is enough to stop the sound stuttering or the lights flickering due to dirt etc. they also said they don't bother to use it. they recommend if you need a longer spell of the capacitor keeping the chip alive, try a 1000uf capacitor. i will do so, but not got to my local (450km away) electronics shop. i will probably find something online and give it a try

Ok thanks, thats useful information, I might try that myself. Robin

Hi again, just a little heads up, I tried my O8 with a 25v 1000uf and found exactly the same result as with your test using the 75uf version. In other words it was not noticeable. I did the testing over a bad point, (which I can remedy) but was waiting to use it as a testing ground for the capacitors. So I ended up fitting a 25v 4700uf capacitor (which is physically quite large but fits ok in the 08). That worked as I was hoping the 1000uf would, it went over the point I mentioned with no problem, and also kept running for a split second when lifted of the track. Robin

indeed. having seen who supplied the original sound files for the Dapol fitted version, i cancelled my pre order for the new loco's and bought the Paul Chetter chip instead. obviously some people are happy with the factory sound, but there are better choices available
