Sorry Jim it is a Kato HO, an the decoder is a MRC EMD 710 #1613
Thank YouYou made my day, that is what i told MRC
You are going to have to be more specific:
MRC has a 'drop in' N scale decoder for that engine(MRC N Kato SD80 drop in 0001808). And if you have a HO engine, there should be lots of room for a speaker mount. Sometimes the 'supplied' speaker needs to be replaced.. I have had to use a small oval Tonys Dream Speaker to fit in the long hood under the radiator area of some engines(HO).

I assume this is an HO model, and the decoder came with a 1" round speaker?? Unless the model has an opening for a 1" speaker (like say a Kato SD-38), generally the largest speaker w/ enclosure you can fit in a GP or SD type engine is a 1/2" x 1" oval speaker. If you get a good speaker and enclosure, the sound is usually very good from such a speaker.
Trying to install a MRC plugin sound decoder in a SD80MAC,my trouble is there is no space for the speaker to be installed. ANY SUGGESTIONS
