Re: Trying to save a 576


Bob you hit the behavior exactly square on the head. 0-75% intensity control the trace brightens then dims and brighten again and at full intensity it loses all resemblance of focus. So I think this tube is toast. Also this tube has a weird model number it is a 154-0563-05 I cant seem to find any reference to a tube version higher then 2. The High voltage transformer is the black silicone one.
