Thanks for the post, but sorry can you direct me to the correct Tsunami please....
I would replace that board with a Tsunami with 645E prototype engine without turbo. So that would be an A format.
There is not much room in there and that' s just another reason I remove the OEM board first.
I have just purchased an Atlas MP-15DC switcher (CP switcher) which comes as DCC ready (8 pin) Could you advise what is the best decoder for this (with sound) and also to have an 8 pin plug ready (avoiding having to solder!)
