Ed,
I use the Lionel Powerhouse to power my NCE 10 AMP system with no issues at all. I using an aftermarket connector purchased on Ebay to adapt to the NCE power connections. The NCE system use an 18VAC power supply. I had intended to use (and purchased) the NCE Brutus power supply but it arrived damaged. The guys from TTX were great, have been using them since 1998 when I got into DCC in HO.
Kind regards
