We have 7 Mac Tw1’s – four of which are working beautifuly, but three of them the lamp won’t come on. When going through the test sequence you can hear/see it do everything else it should but there is just no light. We have tried changing the bulbs over to new bulbs and the bulbs from the working TW1’s but made no difference, any ideas whats likely to be causing this? We’re thinking maybe theres a fuse somewhere that’s blown but don’t know where that would be!
Also we need some spare parts – new air filter cover and some more bayonet receptive lid closure, where's the best place to source these from?
