I just expanded my starter set and been having issues with original transformer thus even magnified it. Added lgb track kits ( 19902 and 19901) as well as a tender lgb 69575. I purchased a Mrc throttle pack 9900 .

Ok so my issue is when my mrc 9900 in connected, the chuffing sounds like a machine gun ( full throttle)even before the loco and tender hardly moves? If I connect the original lgb transformer (5003) with 4 foot circle the sound is realistic respectively with speed (SynchronizEd)?

Help……

Sound units will go to full throttle on some supplies as they have pulsed power output. If momentum is on, turn it off to disable the pulses. If this does not work then install a PWC filter to eliminate these pulses.
