The Wall o' Williams got a new resident on Saturday. Thanks to a KLOVer from McKinney (a suburb just north of Dallas) I was able to make a quick run to the slush capital of Texas and returned home with the Sinistar pictured below.
It had been retrofitted with a switching power supply, so the first thing I did when I got it home was unplug the switcher and put a rebuilt Willliams power supply board back in. Props to the person who did the conversion though, it was not the usual operator hack. It was well done. There was a connector on the AC line input (which was tapped into the monitor AC lines) and there was a 15 pin adapter to convert the switcher power outputs to the Williams pinouts so it could use the original power connector. He also left the power supply board and the heat sink with the transistors so all I had to do was remove the old power supply board and replace it with a working one and reattach the connectors. It fired right up and has been working fine.
I had to tune the monitor up a little and came up with a question. It is a Hantorex vertical mounted monitor but it has a bright fuzzy line (more like a smear) on the left side (that would be the top if it were mounted horizontally). I wasn't able to adjust this out. Is that normal? If it can be tuned out, then what controls will adjust it out? I tried to get a picture of it shown below. It is the red vertical line in the picture below. I'd really like to clean it up as it is the original monitor that came with the cabinet. It has the same Williams serial number as the cabinet.
