I am looking Australia Power Adapter suitable to my Bachmann Train Power Pack & Speed Controller 46605A is 16V and 1amp maximum or minimum amp due overheat 1 amp current or increase to 2 amp is normal current. Also what is DC plug size to Speed Controller DC socket. It is some old laptop power adapter unit is 16V output and up to 5 amp less DC plug size suitable to E-Z Command unit at eBay selling. I don't like new power adapter 240VAC - 16VDC 1 amp selling fake at Hong Kong eBay.
