I PUT THE CHASSIS ON A TEST JIG FOR THE SECOND SOFT START. I GOT A DECENT PICTURE ON THE TEST JIG. I PLAYED THE SET ON THE JIG FOR A FEW DAYS, AS IN SMOKE TEST. THE CHASSIS WAS THEN REINSTALLED IN THE CABINET.
THERE ARE A FEW BUGS I NEED TO WORK OUT. WITH AN "INDIAN HEAD" TEST PATTERN, I SEE SEVERE GHOSTING. THE RF OSCILLATOR TUBE (6LJ8) HAD HEATER/CATHODE LEAKAGE IN BOTH SECTIONS AND I COULD NOT FIND A REPLACEMENT IN THE JUNK BOX. THERE MAY BE A PROBLEM WITH THE DELAY LINE.
AS SOON AS I FIND A GOOD 6LJ8, I'LL CONTINUE DEBUGGING. AS A RESULT OF THE GHOSTING, I COULD NOT DO A REALLY GOOD JOB WITH THE CONVERGENCE.
DESPITE THE BUGS, THE SET IS VERY WATCHABLE. I WILL GET A PICTURE OF THE SET WORKING AS SOON AS I FINISH DEBUGGING. I THOUGHT I HAD A GOOD WORKING PIC, BUT WHEN I GOT THE PRINTS AND CD, I REMEMBERED SNEEZING AS I TOOK THE SHOT.
BTW: I WAS USING A SERVICE MANUAL FOR A MONTGOMERY WARD SET (AIRLINE). THE CHASSIS IS SIMILAR. THE ONLY DIFFERENCE I SAW WAS LACK OF "INSTANT ON" ON THE PRINT. THE "INSTANT ON" FEATURE WILL BE DISABLED DUE TO FIRE HAZARD.
IT TURNED OUT I HAD THE CORRECT PRINT FOR THIS SET IN MY MOTHER'S BASEMENT.
ANOTHER UPDATE: THE DELAY LINE WAS BAD. I THINK SOME WINDINGS SHORTED, CAUSING THE DOUBLE IMAGE. IT ALSO CAUSED A BRIGHTNESS PROBLEM. BEFORE, I HAD TO KEEP THE MASTER SCREEN CONTROL AT MINIMUM. THE BACKGROUND CONTROLD WERE ALSO SET NEAR MINIMUM. THE MAIN BRIGHTNESS CONTROL HAD TO BE SET NEAR MINIMUM TO KEEP THE PICTURE FROM BLOOMING. I REMOVED THE DELAY LINE AND RIGGED A CAP AND RESISTOR TEMPORARILY. I NOW HAVE A SINGLE IMAGE AND CAN SET THE GREY SCALE AND BRIGHTNESS THE RIGHT WAY.
THE PICTURE TUBE ISN'T ALL THAT GREAT. IT MAY BE SLIGHTLY GASSY. I WILL EVENTUALLY GET IT REBUILT. AS OF NOW, THE PICTURE IS DECENT AND VERY WATCHABLE.
