I recently purchased a 2-4-4 Forney with DCC installed and plan to convert it to a DCC sound decoder in the near future.  Info that came with the locomotive indicate it may be good to remove the filter components (inductor and capacitors).  I cannot seem to locate these components on the circuit board in the tank portion of the loco.  Are the filter components actually on this model and, if so, where are they located?

Thanks.
