I've been using a Full Spectrum MLE-40 to make model airplane kits for 12 years. I replaced the original controller board about 2 years in, and the tube last year (with an aftermarket tube that actually will put out 40 watts). Tuesday morning it wouldn't connect to my PC. Since the inside light comes on, directly connected to the AC, but nothing else works I figured that the power supply went out. I looked to see if the cooling fan on the power supply was turning and found something that I had not noticed all the time I've been using the cutter, the power supply doesn't have a cooling fan!

Has anyone replaced a power supply in one this Jurassic and can you give me a recommendation of a make and model to use as a replacement?
