Reply to "TIU Power Supply"

Even if the engine is started up, it shuts down once the SF Load process starts.  It has been noted by MTH Service that using DC has resulted in less errors when loading sound files.  I use a HO DC power supply feeding fixed one using a fixed DC output.  I use the Bench loader though.  To load a sound file you only need the 7 pin plug installed for PS-2.   I normally use all the plugs though, so I can check all the outputs after sound file load.  G
