I have done a number of these.  First, you should download and print  
the full instructions from the Internet.  The cheesy ones they give 
you with the package don't give enough information.  

It is very important that when you stall your loco to check the motor 
draw (hold it on the track, stop the drivers and measure the amperage 
draw)that it does not exceed 1 amp.  If it does, replace the motor.  
If you are using open frame then you are asking for trouble.  I am 
sure that you already knew and that you used DC for this.

Coreless motors are very good in that they draw very little (20 to 30 
milliamps) and if they have a gearhead, they will allow you to run at 
scale speeds.  There is a bit of gear whine but IMHO, the superb 
operation compensates for this.  (This is another story not for this 
post.)

Good can motors should do the trick as well.  If they are worth 
anything, they should give all the specs.

Next follow the instructions to the TEE.

You need a good speaker to drive the lower frequencies.  Make sure 
that it has an 8 OHM resitance.  Anything less will burn out the 
Tsunami.  (I got that one from Dan Kirlin)  In audio circles, it 
should be the other way around but this is trains and nothing is ever 
as it seems or should be. 

You can use two speakers one in the tender for bass and one in the 
loco for treble.  Two 4 OHM speakers installed in series would work 
but lots of extra wiring, a pain IMHO.

Always be wary of current draw in milliamps especially when lighting 
comes into question.  I have used many combinations of resistors 
depending on the current draw of the bulb.  Once again dimmer is 
better IMHO and the bulbs last longer.  The LED's don't just look  
incadescent yet.

AFAIK, if you burn a Tsunami out, they are warrantied.  However, 
policies change as time goes on.

The fun part is the programming.  There is a lot you can do.  
Experiment and you will eventually find what you need.  It may take 
time but once you get to the point where you have found your groove, 
it's a piece of cake.  

I hope this helps.  If you need more information, they have a help 
line or you could email me or better yet other list members who have 
had more experience.  I believe there is a Yahoo group dedicated to 
the Tsunami.  

I have not gotten the diesel one yet.  But then again...it's only a 
diesel.  Why do diesels need sound?  The gear sounds are good enough, 
L0L;->
