Yes it does. From the earlier illustration - Point A to B is how the signal gets to the horn AND Point W to X is how signal gets to the woofer. You said originally that the woofer worked, so W & X are less of a concern.

After you solder the fullrange jack back in, try touching a short jumper wire from A to B and see if the horn comes on - this will bypass the normalling contacts inside the High jack. If you don't have any luck cleaning or replacing the jack you can solder that short jumper in place.

Iso-propyl alcohol is a decent cleaner, but can strip the metal too clean. A good cleaner like Caig DeOxit removes oxidation and leaves a light lubricant behind that helps protect and preserve the contact. That's why DeOxit is great for cleaning potentiometers. It doesn't strip out the necessary lubricants.

A pipe stem cleaner has enough bristles to clean something that small. A real burnishing brush (specifically for this kind of work) has more of a fine sandpaper feel to it.

Hale-friggen-lujah the speaker is working properly now!! :D :D :D

I bent the contact in the jack to sit in the groove better...cleaned up the contacts with some fine sandpaper, then i cleaned up the plugs and contacts on the back of the board.

The thing is, now both full rane jacks work even though i only fixed one...so it may have just been the plugs from board to speaker...i looked close though and didnt see any significat oxidation/corrosion.....although i know it doesnt take much...just plugging and unplugging can make a difference.

so, with the other speaker, i will unplug the speaker plugs, clean up the contacts, and try that first, before i take it all apart like the other.

The important thing is that speaker works 8)

Thanks for the help Hawk...and all the other guys who helped too.

I'm glad you got there in the end.

Good job y'all....
Another RO member saved from costly repair....
And all the way over in Greece no less
amazing isn't it!

Good luck to you BoomTastic.
I hope all sounds good now and you can get back to doing what you probably really want to do...which is playing!
You hung in there and stayed with it to the end! :D :D :D :D :D

teach a man to fish.......

Good job Boom!

thanks again guys.

just finished fixing the other speaker and the problem has been verified. The speaker plugs that plug into the board had just enough junk on them to not make a good contact.

problem fixed.

case closed.

well done

good efforts from the Hawk
