18 FEB 2008. I REBUILT THE COUPLATE IN THE VERTICAL SECTION. THE ORIGINAL REBUILD WAS DONE ON PERFORATED BOARD THAT HAD FOIL TRACES. THIS WAS MY FIRST MISTAKE. THE PRINT CALLED FOR 0.005 CAPS. I USED 0.0056 CAPS. THIS WAS MY SECOND MISTAKE. WHEN I REBUILT THE COUPLATE, I USED PERF BOARD WITH NO FOIL TRACES, AND CORRECT CAPS. THIS SOLVED MANY PROBLEMS. THE VERTICAL STILL HAS SOME JITTERS, AND OCCASIONALLY STILL TRIES TO COLLAPSE. THIS IS WHEN THE SET IS STILL FAIRLY COLD. AFTER IT'S BEEN RUNNING A WHILE, THE VERTICAL IS AS STABLE AS IT CAN BE. I ALSO REPLACED A QUESTIONABLE 1 MEG RESISTOR IN THE VERTICAL SECTION. I HAVE EVERY REASON THAT IT INTERMITTANTLY JUMPED IN VALUE. RESISTORS AT 1 MEG AND HIGHER SHOULD BE REPLACED IF THEIR VALUE IS MORE THAN 20% OFF. I PLAYED THE SET FOR SEVERAL HOURS AFTER REASSEMBLY. IT IS NOW SOLID AND WILL SERVE AS A DAILY WATCHER. I WILL ADD NEW PICS AS TIME PERMITS.
23 APR 2008: ALL OF A SUDDEN I LOST THE PICTURE. UPON INITIAL DIAGNOSIS, I SAW THE GETTER ON THE 6AU5 (HORIZONTAL OUTPUT) CHANGING COLOR. I DIDN'T HAVE A REPLACEMENT IN THE JUNK BOX. THIS PAST WEEKEND, I WAS AT THE ETF CHECKING PICTURE TUBES FOR THE AUCTION OF DAVE JOHNSON'S ESTATE. THERE WAS A CHASSIS WITH A 16 OR 17" CRT. I DECIDED TO CHECK THE CRT. IT TURNED OUT THE CHASSIS HAD THE SAME HOR OUT MY HALLI DOES. NOW, I CAN FIGURE OUT IF THE PROBLEM IS A TUBE PROBLEM, OR SOMETHING ELSE. BTW: THE CHASSIS IN QUESTION WAS ONE THE ETF WAS GOING TO DISPOSE OF. IN THE NEXT FEW DAYS, I WILL DO MORE DIAGNOSIS. IF IT IS SOMETHING SIMPLE, GOOD. I WILL POST MORE WORKING PICS EVENTUALLY. IT TURNS OUT THAT THIS SET IS ONE OF THE MOST UNRELIABLE SETS I HAVE RESTORED. IT WAS NOT WELL BUILT. WHEN IT IS WORKING, IT WORKS GREAT. I HOPE IT'S JUST THAT TUBE. MORE TO COME.
