    I don't know what voltage Australia uses as it's common voltage but if it is 120 volt, there are any number of options available. Jefferson Transformer (USA) among others can provide you with a replacement. A machine tool transformer with suitable VA rating is adequate to your needs.

    For that matter, if it were me, I would not even transform the main voltage down...I would seek to buy a lamp that is of the proper wattage at the main voltage.

    Don's Bulbs (a usefull bookmark!) says this (http://www.donsbulbs.com/cgi-bin/r/b.pl/ekg%7c19v%7c80w~ansi.html) is your current lamp. Good news is that it should be easy to find another lamp that will fit your enlarger as MR16 is a common size (my Durst L1200 uses the same size lamp, but 250W @ 24V). Find a lamp first, then worry about getting a transformer to match (if you need one - some run at mains voltages as already suggested - but in that case, check the voltage rating of any switches). The cost of a new 12V or 24V transformer will be a fraction of having your existing one re-wound.

    Probably best not to go above 100W in case a higher wattage causes overheating and also check that the new lamp is a dichroic type as this allows a lot of the heat to leave via the back of the glass envelope; too much heat coming out the front may be a problem for the enlarger if it is designed for a dichroic lamp (which, according to the link, your existing lamp should be).

    Of course, if anyone has a Vivitar Colour Head service manual floating about and can tell you the secondary voltage(s) of the transformer...

    Cheers, Bob.

    If you want to change the lamp socket and have 120 volt main voltage in Australia than this link will get you lamps that will be of the appropriate wattage and get around the transformer requirement

    If you want to buy a transformer, check out Digikey for prices. They have a good search tool for different types of transformers at:

    Shipping might be a little pricy cause transformers are heavy. But it's worth a look...
