Thanks for the quick reply.  I am going to download the installation manual from the Tsunami site and see if I can make sense out of it.  Should be a fun project...

Curiosly, as I look at the PC Board, I notice there seems to be a spot for a resistor (r3) that is missing it's resistor...  Seems to run great, though!

Hi all!  I'm new to the board and just getting back into model railroading after a 20 year hiatus!  Boy, have things changed!  I just purchased a new Spectrum EMD SD-45 from a gentleman on e-bay.  The part number on the box says it is #82708.  According to the literature it was produced in 2003 and is "DCC Ready".  I understand this to mean that it will easily accept an NMRA standard decoder.  However, when I removed the shell, I see the PC board, but no 8-pin plug like I was expecting...  I would like to put a Tsunami AT1000 sound card in this fella... Is that possible?  Is the PC board an installed decoder, by any chance?  Thanks for any help you can give a newbie, oldie!
