Hello there, First time using the forum.
I have a LGB sound car that I just purchased that I hooked up to my old LGB 2119D Locomotive (ochre lake george and boulder).
It sounds like a machine gun, or I should say like the sound is being played back at high speed. I have a brand new MRC controller, throttle pack 9900, including a new circuit board on the Mogul. Im thinking I might have to install pickups under the boxcar to power it seperatly from the mogul.
I notcied a youtube video of the same boxcar with comments stating that other owners seem to have this same issue, however I cant seem to find a solution anywhere.
Thank you!
Hi Troy,
when you say it " sounds like a machine gun", do you mean the chuffs are very rapid? These simple sound units work off of track voltage. I would suggest to try it with another transformer, preferably an old school analog unit.If it performs normally, my theory is the 9900 transformer is putting out a " pulse" output, which has pulses at full voltage. Occasionally, some things don't always play well together....
The other thing that comes to mind: some of these sound systems will have an adjustment pot on the circuit board that can be adjusted up or down to adjust the rate of chuff. Might be worth looking at .
Hope this helps.

I picked up one of those sound cars overseas while traveling for business. Mine has an option to use a 9 volt battery to power it. Have you pried the roof off to see if yours has the same? It might solve the problem.

Hello,
Thanks for the replies. Yes, the chuffs are very rapid. I have an old MRC transformer/controller and I tried using that as well, I still have the rapid chuffs.
Sorry for my ignorance, what is an adustment pot, and what would I be looking for? To my knowledge there is only the volume control.
Thanks!
I have connected a 9 volt to it with and without hooking it up to the locomotive tender power outputs, and still the same extremely rapid chuffing.
