Most RCA's had bonded (glued on ) yokes so it
may have come unglued.
Also dont loosen the magnets ( farthest back on neck).
It may have a PM held down with a wire tie instead of
adjustable magnets. In any case only mess with the yoke.
If its unglued it takes a different technique........
BTW it also looks to me that the top is NOT a straight line !
