I was worried about the Soundtraxx Tsunami decoder in my model of CNR Number 1. It sounded great, but occasionally it would just stop running.
I thought it might be a heat issue, or possibly an issue with the current draw of the locomotive: The decoder is from the TSU-750 line, because that’s the only decoder size offered with the GE Cummins Diesel sound suite. I had room in the model for the larger TSU-1000 and I prefer to use them whenever possible, but that didn’t appear to be an option.
I wondered why Soundtraxx doesn’t offer the Cummins in a TSU-1000. So I fired off an email asking if it something they would consider doing – and if not, could I get a custom load of the Cummins sound suite into a TSU-1000? After all, it’s just a file on a computer – and it’s not like Soundtraxx has to build a custom decoder to accommodate different sound files.
Sure enough – I could get a custom file loaded, and for a reasonable cost no less: about $10 for somebody’s bench time. The TSU-1000 with Cummins sounds arrived last week and as the photo above shows, I wasted no time in upgrading the electronics in my CNR 44 Tonner.
Obviously, it sounds the same as it did before… and now that I’ve tweaked various CVs it runs the same too. (It is still, however, set to the factory default of Address 3: I packed away my programming track as part of the prep for the home renovation and I won’t be able to change the address until I find it.)
I’m still having a few issues with this unit’s operation but I suspect dirty pick-ups on the wheels. I can’t remember if I cleaned them properly when painting the unit. I’ll check that next. I’ll also check my installation to make sure I haven’t pinched anything in the drive system.
Meantime, the upgrade has given me another quarter-amp of wiggle room in this unit and that’s 25 percent more peace of mind, so I’m glad I did the upgrade.
I’m sure others working on a River Raisin Models S scale 44 Tonner will appreciate knowing they can get a TSU-1000 for it. This could be useful to those in O scale who have a two-motor Rich Yoder Models 44 Tonner, too: I would use a TSU-1000 with Cummins custom-load for one motor, and employ a Soundtraxx MC2H104P9 (1 amp silent decoder) for the other.
Thanks, Soundtraxx, for the excellent customer service!
