### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great value
  

*by S***G on Reviewed in the United States on April 16, 2012*

I want them to include a "micro, micro" plug set for the speakerwith longer wires so I can install them in a car directly behind the loco.Something in black plastic would be great.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Dropped right in my Kato P42
  

*by S***S on Reviewed in the United States on February 27, 2021*

It fits with no mods other then I soldered the motor taps and ditched the gray clip. I placed the round capacitor right where the slight roof hump is in front of the fan which allows just enough room to snap the shell right back on. Happy with the performance and sound at 16bit. Will get another one later for my F40.
