250 volt fuse holders weakened and broken. where do i buy fuse holders? and what could have caused it please? Attached record deck to amplifier, no results, or the cd player. slight sound from tape deck when plugged into phono sockets.

Re: fuse holders weakened and broken
Apart from somebody spilling something on them my best guess would be something in the amp seriously overheating. Check out the power section: transformer, rectifers, voltage control section for faults. The holders can be got at Maplin (uk) or Radio Shack (US), but find the fault first BE CAREFUL it could start a fire!

The owners manual shows a AC fuse for the 8300 as 8amp / 250 volts but doesn't show an external fuse holder for the 8600d. It's unlikely that the 8300 would use a 8amp and your 8600 a 1.6 amp. Double check your original fuse values.
First check to see you can turn the motor by hand. If it is stiff there's something wrong with the motor. If OK then have a look at the motor. If it works on 12 volts or under, you can attach a 9 volt battery PP9 type to it. If it's 6 volts, use a 6 volt battery! (You might have to remove any wires going to the motor to do the test). This should cause it to spin. If it doesn't it's dead. If it does check the voltage supply to the motor. Also check for broken plastic parts anywhere on the deck.
That would depend on the mains supply of the unit in question. If it has a 250 volt mains supply use a 250 volt fuse. However the crucial one is the amp rating. If it was a 300ma fuse installed a fuse no greater than that should be used. If it was a 2amp fuse a 1.5 could be used, but not a 2.5. Many fuses are fitted with a 250 volt rating in areas where it would never go higher than say 50 volts, such as in the secondary winding of the transformer.

If the amp turns on and there is no sound start with the speaker to make sure it isn't blown and work backwards through the wiring and connections up to the crossover circuit (all in one cabinet version). On the head separate versions check for a broken output jack problem. The fuses are 10 amp 250 volts for the 100-120 volt models and 5 amps 250 volts for the 230-240 volt models. NOTE: If you are at all unsure about opening your amp up to work on it, take it in to be serviced. It doesn't sound like a fuse problem to me. Necer work on an amp while the power cord is plugged in. Always replace parts with the proper replacement especially fuses. They are there to protect the circuits. If they keep blowing it means there is an internal problem. Remember that capacitors store a lethal charge and it is easy to touch the wrong thing when you are looking inside an amp even if it has been disconnected from power for a while.
My Air Station blew a fuse also. The fuse that came with the inflator may be a bit too small amperage wise so I stepped up to .25 Amps more which is just a very small increase.
It is really ill advise to solder a wire in the place of a fuse. You are just asking for it.
The way I did it is I went to my local Radio Shack and got a small fuse holder with red leads and 1.5 Amp fuses. I soldered the fuse holder in place with the new fuse. And now I don't have to deal with any more solder. Just twist the fuse holder, take out the burnt out fuse and replace it with a new one. And wahlah. I'm back in business again.
It sounds like you have a broken connection in the amplifier. The first thing to check is the fuse. Sometimes the contacts become weak on the fuse holder and the connection becomes intermittent. Any other troubleshooting would require opening up the amp. Any repairs would require resoldering the broken connection.
It sounds like you're not getting enough power to the amplifier.
With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.
