Hey reflow solder on the two ground stakes on the far right end of the chroma board. These grounds open and kill the 6GU7 heaters.
Very common ailment of the CTC-15, 16, 17 and 25 chassis. It can cause a 'cascade' of events: 6GU7 plates go 'waay positive, driving CRT grids positive (since they're direct coupled), causing CRT beam current to avalanche, which can kill the 3A3 and eventually fry the flyback if left to run unchecked.
