I have to remove the RF shielding off my a1200 motherboard so I can stick an internal scan doubler in it

Question: Will that decrease stablity? I have a fair amount of electrical appliances in the room. Big stereo, 25" tv, PC next to it with 17" monitor, fridge, etc....
Heh, I will install that scan doubler no matter what actually, but it would be nice to know what I'm getting myself into.
