Hi there.

You have have been unfortunate enough to experience an uncommon failure. The bass driver has failed. It is a Black Widow that can have the basket/cone/voice coil assembly replaced as a complete unit. The magnet unbolts from the basket and you bolt on a new one. Classic field service designed product. You will be able to get a new basket from a Peavey equipment stockist. Just ask for a 15' Black Widow replacement basket They cost about $180 here in Australia and you can easily change it yourself. Good Luck and happy jamming.

A FixYa rating would be great for my tech tip to you. Cheers

regards
Graeme

Yes a horn can get blown. This should be 2 pieces, the horn itself and a circular driver on the rear. The driver itself will have what is called a diaphragm that can be removed and replaced. That is the part you want. Open up the speaker and get the part number off of the back of the horn and order the diaphragm from Peavey.

SOURCE: AE 740 types different characters than typed on keyboard

make sure your printwheel is latched securely, turn off t/w, press and hold the margin release button while turning power on to do a reset/self-test. if characters are not right on self test, then you might have a problem with either the carriage or main board.

Have a jvc kd-sc401 connected 10 disc multichanger but won,t load cd,s although you can hear multi changer trying to work pls help.stereo working as should don,t have manual for stereo so don,t know how to...


You need to reset the CD player. Remove the front panel and you will see a tiny hole in the middle of the panel of the unit mounted in the dash (i.e. without front panel). Gently push a ball point pen or pin in to press the reset switch.

I have a JVC (stereo, radio, cassette, recorder) and it's buzzing


If it is only when the tape is running, it could be motor noise.
Worn bearing in the motor or maybe a suppressor has failed, if it has one.

Need help replacing keyboard of acer 5536


I found them on ebay in 2 seconds. Ebay usually will have whatever you need. I'm sorry to say that this may not be a fix though. Most likely yes, but possibly not. What exactly is your keyboard doing? You should also know that even though your computer is functioning now, if you do not get the spillage cleaned off the motherboard it will cause the board and whatever components it got on to corrode. It's possible that it may not have gotten into you computer but I doubt it. How bad was the spill? It is also possible, depending on what the keyboard is doing exactly, that you may not need a new KB. It maybe just a good cleaning or cleaning out the KB connector.
