KV27V26 with Bose Wave radio sitting on top... when Sony is off, in
standby, Bose receives severe heterodynes on lower AM sigs.
Interference is warbly, wandering, varies with small line voltage
fluctuations, but generally is overbearing warble sound on top of am
signal. Definitely the Sony, as unplugging it's power removes the
problem.

Bad cap no doubt... but where?


May actually be fairly normal for this switchmode power circuit to interfere
with a nearby AM radio. You may need to reposition or re-orient the radio.
