Many of the RCA sets used a bonded yoke to the CRT. The convergence was
factory set with a tape-magnet on the back of the neck. Once the purity
and convergence was factory set, it is no longer adjustable. There are
some ways to sort of offset it with some strip magnets, but this is a
lot of work, and would require the skills of someone who is very
experienced.

As the CRT and the scan circuits age, the convergence may change a
little. The errors would be more noticeable in the corners. It is not
worth to invest time and money in to one of these older sets.

There is no convergence setting on that beast! RCA uses a magnet strip
at the factory, no tabs to turn. Being a 25" it may not have a bonded
yoke and if not, that would be your only hope. If it's shifted over
time you might be able to loosen it and move it forward or backwards
some to correct the problem. Keep in mind there's around 1000 volts of
low amperage AC applied to the coil on that so, careful where you put
your hands. If the yokes bad, there is no part number for it so, you
can't replace it.
