Great news Max! So just to make sure I've understood: The replacement decoder is another LokSound XL 4.0 "O/G scale" driving a ball-bearing/Alnico Pittman motor? And the new decoder doesn't make the loud "stepped buzzing" of the motor that was heard in your video of the first decoder with Back EMF turned on? So do you think the first decoder was faulty?
Sorry to make a meal of this but I am at a fork in the road and I want to be sure to make the right call. This is partly due to the fact that TCS WOW and Econami 4Amp decoders don't have the EMD645 non-turbo sounds for my GP38s yet. Plus I really like the ESU sounds.
It's a sport, it's a sport, it's...
