Does anyone know the wattage values for the resistors that are in the Lionel 5F test station especially for part numbers 5D-40 10 ohm adjustable power resistor and the part number 5D-39 25 ohm power resistor. Also does anyone know what part can be used as a substitute for part number 5D-16 whistle choke and part number 5D-38 meter choke. I am looking at the schematic for the unit in an attempt to source modern components and to build one of the units. I have found good info on this site about the unit and some folks seem very knowledgeable about the units. Thank you for your time
