Just curious as my experience hasn’t been the best with the Tsunami 750’s.

Fergie,
TSU-750s are the only sound decoder I’ll use. The only problems I’ve had have been with programming them through a Digitrax PR3, and this was resolved when I upgraded to an 18v, 1 Amp power supply for the PR3.
Could you outline some of the issues you’ve been having with your TSU-750s?
Cheers,

You might consider the DCC Electronics forum. This forum is more for Geberal questions.
Like was asked, what are the issues? We are not mind readers.
I use the 750’s with no issues. I use the NCE Power Cab for control. No programing issues.
The 750’s are known to be heat sensitive and there are fixes mentioned in the Yahoo SoundTraxx Group that takes care of the issue.
Knowing what you are doing is a big help. A lot of DCC is not plug and play, though it is for those with the experience.

Lot of locos that draw low current in normal operation will exceed the limit of the TSU-750 if stalled, which can happen with a heavy load on a grade, or if you quickly reverse. The 750 seems very touchy about the current limit, so for really low power locos like the Canon-motored Stewart Baldwin switchers it’s probably awesome, but for Athearn - not so good.

The TSU-750 is only good for motors drawing 3/4 of a amp or less.
So if you have motors that draw over that, you are going to have problems with them.
I just put one in my Atlas S-2 and so far so good. Of course this was the install featured in the Dec. 2010 issue of MR.
