clock radio with slow "put put put" motorboat
sound in speakers with radio OFF. no visual
indication of bad components or bad solder
joints. have replaced two electrolytics nearest
power transformer but without a schematic and
voltages at checkpoints, still no success. any
help? it's an emerson CK5235.

Check the pass element that powers the radio
when you select 'radio' as the alarm.
Sounds leaky.
