THIS WAS A SCORE FROM THE EARLY TELEVISION CONVENTION IN 2006. BACK IN THE DAY, I HAD ONE SIMILAR TO THIS, BUT THE ONE I HAD, HAD UHF TUNING.
THE CRT CHECKED LIKE NEW. THIS IS A HOT CHASSIS SET. THIS USES THE SWITCHED NEUTRAL VERSION. THESE SETS WERE NOTORIOUS FOR THE CHASSIS COMING IN CONTACT WITH THE CABINET. IF YOU RESTORE ONE OF THESE, YOU MUST DO THE HOT CHASSIS FIX.
I SOFT STARTED THIS AS USUAL. THE VOLTAGE DOUBLER WAS DEAD. I REPLACED IT AND GOT REWARDED WITH A CAN GETTING HOT AT REDUCED VOLTAGE. I ABORTED THE SOFT START AND PROCEEDED WITH RESTORATION. THE HOT CHASSIS ISSUE WAS FIXED AT THIS TIME.
THE NEXT THREE SHOTS SHOW THE CHASSIS BEFORE RESTORATION.
FRONT OF CHASSIS BEFORE RECAPPING. THE SELENIUM RECTIFIER AND A REPLACEMENT CERAMIC DIODE WERE REPLACED WITH SILICON DIODES.
BOTTOM OF CHASSIS. AT THE UPPER RIGHT, THERE WERE CERAMIC DIODES. I REPLACED THESE WITH SILICON DIODES.
THE IF BOARD. THERE WERE A FEW CAPS THAT NEEDED REPLACING HERE.
THE CABINET WILL EVENTUALLY GET REPAINTED. I WILL USE AUTOMOTIVE GRADE PRIMER AND PAINT. SINCE IT IS TWO-TONE, I WILL MASK OFF WHAT I NEED TO. ANY RUST WILL ALSO BE TREATED.
I RECAPPED THE SET AND REPLACED ALL ELECTROLYTICS. I WAS NOT ABLE TO RESTUFF THE CAN DUE TO THE SIZE OF THE REPLACEMENTS. I HAD INITIALLY MISSED A CAP IN THE VERTICAL SECTION. THE PICTURE WOULD START ROLLING UNCONTROLLABLY IN THE CABINET. REPLACING THAT CAP FIXED THIS.
THE TUNER AND CONTROLS WERE DIRTY AS HELL. IT TOOK SEVERAL TREATMENTS TO GET THE TUNER CLEAN. THE FINE TUNING CAM WAS FROZEN. I GOT IT FREED UP AND IT NOW WORKS PROPERLY. THE LOCAL/DISTANT SWITCH WAS A PAIN TO CLEAN. SEVERAL TREATMENTS GOT IT.
THE LOUDSPEAKER HAD SEVERAL TEARS IN IT. I WAS ABLE TO REPAIR THEM WITH SILICONE.
I DID NOT GET AFTER SHOTS WHEN I RESTORED THIS. I WILL EVENTUALLY. THE SAFETY GLASS MAKES THE PICTURE LOOK DARKER THAN IT REALLY IS.
