Original poster: Thomas <tom-at-pwrcom-dot-com.au> Looking for a 240V variac I came across this: http://cgi.ebay-dot-com.au/ws/eBayISAPI.dll?ViewItem&item=2590216386&category=50926 is it a phase angle conduction control (like a light dimmer) or a true 0-240V adjustable sine wave o/p? Anyone? Tom L.
