Hi Mike,

My memory wasn't so bad after all. I just found Tristate's site on the internet at http://www.tristate-electrical.com
Their online catalogue isn't detailed enough to be sure about a suitable unit but the catalogue No. STNP8632 looks a possibility. This appears to be a 230/115V unit which when wired in reverse would give 230V from a 115V outlet (providing power rating is adequate). From memory this was the approach I used. You would need to have someone suitably qualified to safely mount it in a suitable box with appropriate connectors. Listed price of $64.50 seems to line up with the unit I bought also ($40 something in '92).

Cheers
