Henk, I was researching my Corcom F2280 on the internet and came across your 2004 message: --------------------------------------- Who can help me with an EMI filter from an IBM 5110 ? Mine has an internal non-repairable short circuit. This EMI filter is a CORCOM type F2280 and is located in the mains entry box underneath the screen tube. Any one ? Thanks Henk --------------------------------------- I have one, if you're still interested. Bob
