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!

Part of your PowerSupply is Frito.
Probably the +/- 15 volt rails, could be other.
Check inside power voltages, probably some regulators are gone.
Preferably get a tech unless you have the know-how and test equipment...
One important note to be aware of Polarity. DC connections are Positive + and Negative -. RED/Black and/or White wires. Yellow is usually Video. Do not Reverse the polarity as this can cause mismatches and/or short circuits. Disconnect your attached wires and re-attach them correctly and firmly. Wires must be set into or onto the posts or connection points correctly by + or - and they may not touch one another. Check the Reset or Fuse on the amp and make certain you have full power.
If you fail to polarize correctly, you could damage the speakers moreso than the Amp.
No! Unless you have read it wrong and it should be 320V. You can go higher than 250 volts but not lower. And you can go lower say to 10A and say up to 16 or 20A, though you should stay around 15A to be safe. If you do fit a 10A fuse at 250 volt and it blows straight away then it won't be the fuse that is faulty, but something inside the amp that has gone. As fitting even a 15A 250V will do the same. A 32 volt fuse in the mains section will burn out in a fraction of a second.
For connecting these to your amplifier you need 4 Stereo RCA Cable.
1.Connection for cd: Take one of the RCA cable connect the one end (red/white) jack to the line out of your cd and connect the other end (red/white) to the CD input of Your amplifier.
2.Connecting the tunner:
Take one of the RCA cable and connect the one end (red/white) jack to the line output of you Tuner and connect the other end (red/white) to the TUNER input of your amplifier. 3. Connectiong the tape deck:
Now you have two RCA cable. Take one of the RCA cable and connect the one end (red/white) jacks to the PLAY out of the Tape deck and connect the other end (red/white) to the TAPE 1 play input of your amplifier.
Now connect the last RCA cable. Connect the one end (red/white) jack to the record input of the TAPE deck And connect the other end (red/white) to the TAPE 1 Record input of your amplifier.(this connection will help you to record to tape from cd or tuner. if you are not interested in recording then you can avoid this connection.)
Now you can select these three items from the frond plannel control switch of the amplifier.
As long as the phono input is only being used for a record deck the most likely cause is a faulty magnetic cartridge pre-amp. If you are connecting any other device to these sockets, remove it and place it in another socket. If you haven't got enough sockets you can get a switching box to solve the problem. If you are getting the problem due to a record deck, make certain it hasn't got a built in pre-amp first, check the cartridge and wiring to it and all deck connections. If still no luck then you will find that you need to replace the pre-amp. It will be a single IC, which can be found by following the wiring from the phono sockets inside the amp.
Well, take good look at the Fuse itself on metal area.
If it says AGC, then fast acting.
If it says MDL, then Slow Acting.
If you cannot figure it out, then just use Fast Acting since it is more commonly used in smaller Receivers and Amplifiers and Fast Acting will cutoff faster (compair to Slow Acting) if there is any unknown Prblem with Chassis.
I do not think your use of an equalizer has caused any problems. I will explain the proper use of the source/direct button. This button's function is to monitor the output of a recorder connected to the record outputs of your amp. When this button is pressed on the sound going to the speakers comes direct from the "source" (cd, radio tuner, phonograph etc.) when in the off position you can monitor the recording of whatever source is being recorded via the tape deck. This switch must be off to record through the amps record outputs.
To test this, put a blank tape in the tape deck, choose the source as phono and place the dec in record/pause. With the source direct button pressed on you should hear a change in volume when moving the amp's volume knob only. When source direct is off you will be able to hear the output of the tape deck, so adjusting the tape deck's record level will also affect the volume coming out of the speakers. more record level in/ more level out.!
Below is copied from page 9 of your user operation manual for Marantz's explanation of the source/direct button.
