    If switching bulbs eliminates the problem, that doesn't sound like a timer problem. The timer circuit in the power supply is there to switch a relay to supply power to the bulb. To troubleshoot, you would have to reinstall the flakey bulb. Before you do, look carefully at the pins on the bulb. Are they pitted or dark? That could be caused by a socket on its way out. The socket in my CLS450 head has been replaced at least once, and so has the relay in the power supply.

    If it lights reliably when first used, I would strongly suspect heat expansion in the socket causing an intermittent electrical failure. Also check for cracks in the socket.

    That will do it. Time for a new socket.

    Geez, where am I going to get a new socket? Never mind because I'm in Australia, I have to wonder where anyone would get one anywhere. I mean, is this a Durst part, or is it something I should be able to sort out through some specialist supplier? Really I think I'd prefer to be using a 100w lamp. Any advice?

    It's a Durst part, but also a standard part for halogen lighting. I can't recommend anywhere specific, but lighting stores might be able to help. Just make sure the socket you get is rated for 100W (most household halogen lights are much lower in power).
