 THIS WAS FOUND AT A NOW GONE FLEA MARKET IN COLUMBUS.  AS FOUND, THE CRT HAD A BRIGHTNER.  IT CAME BACK AFTER A LENGTHY COOK AT RAISED VOLTAGE.  I SOFT STARTED IT AND ONLY HAD 15 VOLTS ON THE DOUBLER.  THAT CAP WAS DEAD.  I DID A FULL RECAP AND GOT A NICE BLANK PICTURE.  AS YOU WILL SEE BELOW, THIS CHASSIS IS NOT SERVICE FRIENDLY.

 THE PC BOARD GETS A LOT OF HEAT... LITERALLY.  THIS BOARD WOULD BE MY NEMESIS.  THE HOT CHASSIS FIX ONLY INVOLVED POLARIZING THE PLUG.  ON THE BOARD, I ENDED UP RESOLDERING A LOT OF CONNECTIONS.  ULTIMATELY, I GOT A DECENT PICTURE.
