A bad transformer seems unlikely. Would suspect the power supply first for high ripple or AC. Should be easy to check with a meter. Think these older RCA power supplies used large paper caps that become open and are in a potted metal box which make rebuilding them an awful job.
Other possiblility I can think of is the shielding of the cable from the pickup unit. See if it has a shielded wire that has become loose or broken. Richard
