My son turned up the volumn on the Receiver and blew the speakers! I want to replace them in both floor speakers. The speakers were purchased in1968. Where can I buy the replacements speakers? Does your repair manuel have an exploded view of the wiring, etc.? Thank you.... Evan Monkemeyer

have blown speaker some one turn it up to high and blew it replace it and what the volumne

Fuses blow due to an overload. What has happened in you case is one or more of the output devices (found on the big heat sink) has shorted and acting like it was a piece of wire. Now you have to find out which. By the way it might have gone due to bad speaker wires or speakers, or speaker wires touching each other.

Sounds like a shorted audio IC or bad connection in the limiter circuit.

The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

A crackling speaker is a blown speaker i think he might have either used them to much or listend to them to loudly

If the speaker has been overdriven, it may have damaged the cone surround or damaged the speaker coil, causing it to 'rub' inside the magnet. To check for rubbing, you need to move the speaker cone backwards and forwards by hand and listen where the speaker coil/cone goes into the magnet. It should be silent if ok. If you can heara rubbing or grating noise, then the speaker is damaged. If the output driver on the amp is damaged it can give a distorted sound, which could easily happen if it tries to provide too much current.

when turn on the amp,the volumn cannot under control

When attempting to increase the volumn on the television either using the remote of turning the reciever knob by hand the volumn increases dramatically. I am concerned the speakers might blow. Does anyone know how what the problem might be.

The powered subwoofer should be connected to the black subwoofer output near the bottom of the receiver in just about the center. A subwoofer uses line level signals and has its own amplifier, Good chance that you wiped out a channel. Put the wiring back the way it was, and IF the channel was not directly connected to the speaker terminals, MAYBE, JUST MAYBE it will still work.
Chances are slim...
