  1. Yes I'd thought about that but I then realised that the OO chip probably wouldn't have the power for an O gauge twin motor loco?
  2. Thanks for all the clarification - much appreciated. Hopefully one day this sound project may become available as it sounds marvellous - the LB Deltic project is superb, but the only other decent option at present for O gauge that I've heard (and tried) is the Howes project, but it just doesn't have the drivability/control that the Legoman project does and it would be good to have more than one decent Deltic sound for O gauge.
  3. I'm wondering/hoping if the Deltic sound project will be made available so we have a second decent sound project for installing in O gauge Deltics?
  4. Many thanks indeed Paul that's very helpful.
  5. Does anyone know if these are the tanks that used to be seen at Kings Cross diesel stabling point in the 1970s/early 80s or would those have been TTAs? Thanks, Phil
  6. Very strange - glad you managed to get hold of one though. Cheers, Phil.
  7. That sounds odd - it was sold out at Heljan some time ago I understand (i.e. sold out in terms of pre-order supplies to retailers) and because of a large number of returns due to the locos shifting in the packaging and causing damage to buffer-beams and other delicate areas (the plinth spec was not what Heljan had specified to their factory apparently and securing bolts have been pulling through the plinth and allowing the loco to move in transit), the blue version is now sold out everywhere I have looked. This applies to the non-refurbished version (3105), not the refurbished version pictured
  8. Thanks Trevor - I was just wondering if he air brushed it or if there was some other method - will drop a comment and see what comes back.
  9. Thanks Trevor that's very useful indeed. I'm guessing this guy gloss varnished the tender and loco before applying decals?
  10. Thanks guys - all very interesting indeed. Having never been inside an engine room I had no idea how this would all work. I shall look under the bonnet of my car with renewed interest now! No sunroof fortunately!
  11. As the title suggests, I'm wondering if this is the dumbest question ever posted here, but I'm going to risk public humiliation and ask it! On the roof of all diesel locos is a big twirly whirly ventilation fan which is located beneath a very large hole in the roof. How is rain water prevented from entering the gubbins below and/or prevented from ending up on the engine room floor and accumulating wherever it lands? Same question for cant rail grilles, body side grilles and vents on the front of locos (e.g. the vent on the top of class 47 cabs) - I can appreciate that
  12. And now a short video with the body on - which makes it sound even better despite a small echo effect. Just need to figure out how to make it run smoother at low speed (I read somewhere about wiring the motors in series on Heljan O gauge locos to help this?), but that can wait - for now I'm just enjoying the Napier noise! So in sum total to get this sounding right it was a switch from NCE Powercab to MRC/Gaugemaster Prodigy Advanced 2 that reduced the weird high frequency noise (but didn't get rid of it completely), EM2 speaker at one end which muffles the high frequency noise even
  13. Thanks Charlie and thanks also for your patience and support - great stuff.
  14. Quick video clip. Gaugemaster Prodigy 2 with EM2 and large O gauge speaker. Foam over speaker mutes the high pitched noise even more without significantly impacting overall volume. OK the root cause of the issue hasn't been completely solved but this will do for me and in real life (as opposed to a mobile phone recording) it sounds great. Hope this is helpful to someone.
  15. Partial success - hooked everything up to a Gaugemaster Prodigy Advance 2 and you can still hear the high-pitched whistle, but its a lot less obvious and doesn't drive you round the bend so much, as it doesn't cut through the usual DCC sound white noise so much. Then as a last test, having tried a grand total of 6 different O gauge speakers with the whistle still there on the NCC Powercab and the Prodigy , I hooked up an EM2 - no high-pitched whistle, just blissful Deltic noise! I can only assume that the extreme bass of the EM2 masks the high frequency of the high pitch whistle.
  16. OK today's update - no joy with the filtered 4 board as I suspected, so that only leaves the PSU as the culprit I guess? Although why this interference should only be present on this one chip is very strange. Only option left is to try a different DCC system. I've should have access to a Prodigy setup at the weekend so will see what happens with that.
  17. Thanks for the message - no the decoder has been removed from the loco (where it made the same noise) and is just running on the bench now with direct wiring from the DCC system. Cheers, Phil.
  18. Interesting. I have tried the DCC setup at work and same result, so this points the finger of blame ever closer at the PSU - although I will look at CV9 as Rob mentions above when I next get a break. I'm not expecting miracles from the filtered 4 board given that this looks more like a PSU rather than a mains issue, but we shall see.
  19. Many thanks Rob and Chris that's very useful and interesting. I'm using the power supply that came with the NCE Powercab (I have a Tam Valley booster but I'm not using it here) and given that the high pitched noise stops when the mains PSU is removed (the on-board stay alives keep the sound going) its almost certainly that the PSU or mains supply is where the issue lies. I've got a filtered 4 board arriving soon so will try that and also look at the ferrite sleeves that Bif mentioned. If it is the PSU then I'm hoping that may be a relatively easy fix. I've tried a different circu
  20. Thanks Bif - really helpful suggestions and thanks also to Charlie who has been a star (and I'm still feeling guilty about sending back two perfectly good chips for him to test when clearly it looks like the problem is at my end). I will go belts and braces and fit the ferrite style filter and a filtered mains lead assuming the garage circuit or a.n.other supply doesn't solve it. Yes will definitely post the outcome here if I can solve it - your O gauge Deltic project sounds so amazing that I have to get this sorted one way or the other! All the best, Phil.
  21. Hi Charlie all functions are off on the Powercab except F1. I really don't know what else to try except a different DCC system. If anyone here lives in Hertfordshire/Bedfordshire and has a DCC system that isn't NCE and is happy for me to pop over please let me know!!
