It is probably the resistor 48; there is nno such thing as an Alphanumeric designators in the sch.
I looked at the sch of this radio (code 123) and at this point I do not understand how a 0.05uF capacitos across the pilot (it is #49) would do anything to the hum.
Introducing a ripple current that leads the current through the 53 Ohm by 90 degrees (and is lower by 3 OOM)...not sure how effective that would be.
But does not hurt to try....

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
