hi all,just how important is the metal tube sheilds that go over a tube. reason i ask is my ctc15 silvertone has had an on and off problem with colors turning into blotches after warm up so i narrowed it down to the chroma ref ocillator tube that has a shield and when the blotches start they stay until cooled down. this time the blotches were there and warmed up and i took the shield off the colors were fine then put it back on or just move the sheild near the tube and the color blotches.so i left it off and so far its ok, anyone ever heard of this befor. the socket is fine as i jiggle the tube and nothing happens but like a magnet just putting the sheild near the tube distorts the color.
