Need a speaker for Whistler Pro 73 . Do you remember the old Charlie Brown cartoons? Do you remember what the teacher in the class sounded like? Well thats what my radar detector sounds like. I think the speaker busted. Where can I buy a speaker?

The bad news is it could be any of them. or it could be the lighting- CFL's and regular flourescent lighting are bad for audio, as are switching supplies used in TV's, microwave ovens and some musical gear. They are worse than lighting dimmers for noise.

The thing to do is start at the speaker itself and work through the chain of devices to find the one distorting. An old transistor radio is useful here. Most actually do have enough power to faintly drive a large speaker- listen for scraping and rattling- it would mean the voice coil windings may have come loose or the coil form is damaged from heat.

Move back to the amp input and try again- this time listen for a clipped sound if the speaker checked out okay. It would sound like the Charlie Brown adults in the cartoons. That would be a failure of an active component in the amp. If you now hear rattling or scraping- the speaker voice coil is bad and should be repaired or replaced.

If it sounds good, move back to each deck. apply your radio- volume turned down to an input it one is provided. Each should sound clean like the amp did. If no sound or distorted sound is found here- which is the most probable location, it is likely one of the IC chips is at fault. Likely a 4558 if an IC fault, otherwise suspect dirt or hair on the encoder connected to the spin platters.

Check the Red+Yellow+White cables, make sure they're all in the correct place. Also with your remote control, go to the menu, just play with it a little till you reach the sound menu, put bass a little higher... etc!
