This is regarding some alarm clock radios I have (I collect various models).
They're all from the late 70s & early 80s.
For some reason when some (not all) of the AM/FM radio alarms go off, they have an initial pop sound through the speaker.
I've recapped them and tried a 10uf cap on the speaker to try and filter the pop out, it does lessen it but it's still there.
I've had numerous radios and boomboxes do this when powered on but it's less noticeable when you're already awake.
The all work well but this is an annoyance I'd like to get rid of if possible.
I'm assuming it's an initial surge to the speaker that needs to be bled off.
Does anyone have any ides what would cause the pop and/or what I could do to get rid of it?
