I got the replacement parts in for my Aqua 40 Watt UV Sterilizer and its working now.
For anyone thinking about purchasing one, I highly recommending spending the few extra bucks to buy the optional "wiper wand". This is a simple pull bar assembly that allows you to do a quick cleansing wipe of the crystal sleeve that surrounds the UV lamp, without having to disassemble anything.
After seeing how fragile the lamp and crystal sleeve are (esp. on the longer models like my 40 Watt), the wiper wand option will pay for itself in piece of mind alone.
As my model came without the swipe option, I'll have to remove it from its perch under the tank, pull the sleeve out of the housing and carefully wipe it down to remove the mineral/dirt deposits. With the sleeve and lamp running about $50 each, I'll want to be real careful!
Last item on the wait list is the 3D background, which should be at my door in a few days. 'til then..
