Classic IDX Question - Technical

[MikeK]

Hi all: I recently purchased a used Classic IDX and last night replaced the corroded box screws with stainless ones. After getting in the last screw, I turned on the detector and the thing sounded scratchy and very noisy (via the speaker). After fooling around with it for a while, I discovered that, with headphones it worked fine. Before performing the screw replacements, the detector speaker worked just fine.

So, I shifted the speaker over so that it's now off-center from the speaker holes in the box, but it seems to work again.

It sounds like the speaker may have shifted when I unscrewed the old screws, maybe touching something else?? A ground? Is it ok that the speaker isn't centered over the holes in the box?

Any help would be GREATLY appreciated.

Many thanks, Mike

Since you are using headphones what difference would it make. I still would check why it works off center and not centered, Loose connection etc. Rob

shifted the speaker due to not having the speaker clamp pieces in place. The speaker screws tighten the claps that hold the speaker in place.

If they are loose, the speaker could rattle around (vibrate) against the housing and cause the noise you heard. It's a simple matter to open the housing back up (removing the 8 housing screws) and reposition the speaker and tighten it down.

Doing so would eliminate the possibility of sand or moisture getting inside and onto the circuit board. Id fix it so that the weatherproof speaker covered the holes as designed.
