Clock radio speaker output reduction:
Note that a good number of the smaller clock radios use
higher-than-usual speaker impedances. sometimes upward of 60 ohms: saves
output devices having to handle heavy currents (relatively).
T'were it me, I'd obtain a 500-ohm 'trimmer' pot - the kind that is
meant to go on a printed circuit board, be adjusted once, then left...
500 ohms at 1/4W would be fine - then put it series...
If you really want to get fancy, you can put a small switch in the case,
and short out the pot, thus restoring the radio to full volume if
desired...
Thanks very much. This idea will do just dandy.
PS: this presupposes you are comfortable with
soldering....
I'm by no means an expert, but I ain't afraid of it either.
