had as few of those in the shop years ago.pretty good sets.check your high voltage.triplers can weaken and give apperance of other issues.clean vertical controls with de oxit.there are 2 little black caps that are side by side in vertical deflection.these often fail.dont know the values right off hand.there is a chip in the demod that would give loss of color also.i had one that our top guy swore was a crt.we changed it out and same problem.weak tripler.replaced tripler and the crt was weak!original was good.swapped back and set was fine.one of the few dave was wrong on.i remember 2 in 30 years
