If you read my thread about fungus removal a few months ago, you'll know how much this stuff gets in the way of a nice picture!!! Have a search for fungus if you don't know what I'm referring to and you should find out. When i got my seleco svp350+ the green sony tube had fungus on it and subsequently anything white had a green glow around on it and things looked decidedly blurred. One of the things I was worried about when I put it back together was that I noticed the paint on the metal inside the coolant housing was stripped. It looks like its the culprit and small bits of fungus are developing again. So... bad news is I have to re-de-fung this green tube. Good news is I can take lots of lovely piccies while I'm doing it!!! BIG QUESTION FOR EXPERTS HERE: Anyone know where I can get hold of the blue-coloured glycol coolant to fill this tube with fresh coolant instead of filtering the old again? Thanks!
