Hi, I have Meopta Magnifax 4 and its original transformer for colour head. Lately I noticed light getting brigter and darker in nonregular short intervals (parts of second). I guess my house power lines or transformer doesn't give stabile power. What is best ways to stabilize power? My thoughts goes to two directions: 1. Computer UPS, 2. Do you remember in old days of vacuum tube TVs those power stabilizers, you connect them into power wall socket and TV into those gadgets. And what if house power is stabile, but transformer gives unstabile output? Any other efficient way, and does anyone tried to use computer UPS for enlarger? In theory it should work, but does anyone knows that in practice?Yes, I know there are stabilizers for enlarger transformers, but as any gadget which has "photo" label, they are extremely more expencive than same gadget without "photo" label Thanks.
