Jahn Henry sound?

[nw-modeling-list at nwhs.org]

I have a model of the Jahn Henry and now with Soundtrax' new tsunami 
decoders I am very interested in installing a sound decoder in it.

Can anyone help be with a source of digital sound already available 
or lacking that is there a video tape or DVD available with the 
sounds of the coal turbine running?

Any advice would be greatly appreciated.  The Jahn Henry is the only 
N&W loco I have.  I love it because it is so huge!!  I am not on your 
Yahoo group.
