Unit probably uses fuse type lamps, either 8 or 12 volt filament. Remove one of the lamps and look for voltage rating on end cap. You can order these lamps from Allied Electronics or MCM Electronics online

Marantz amplifier PM68 replace fuse


You don't see any glass fuses? There is also a non replaceable fuse in the power transformer.

No dispay only if very dark


It's VERY possible that the Tuner has a "backlit" display ( Like many of the 1980-90's Yamahas)...You'll need to replace a couple of small bulbs inside

Standby light is flashing on my marantz sr7001


hi,
First of all remove all the speaker connections from the amplifier. After that power the amplifier and check the Standby blinking (protect) show or not . if not, then any of the speaker is damaged also check the wire for any short circuit . If then also its goes to protection then it have some hardware truouble inside.

Amplifiers gose protect mode , when there is a hardware fault in side it. Its a warning that some thing is wrong.
Normally amplifiers show this when any of the output amplifier have some problem. there 6 amplifiers in this receiver . May occur when the output diver transistors of any of the amplifier become shorted. if the output transistor get shorted this will lead to flow of current through the speakers. To prevent this there is a protection circuit for each channels. One combined output of this protection circuit is connected to the system control. when the any of the output amplifier fails, the protection circuit detects it and switch of the speaker and sent data to the system control. when the system control get this data it will give a warning to the customer through display that PROTECT.
You have to check the amplifier.
For that you need digital multimeter,soledring iron screwdrivers etc
Open the amplifier , then power it on. Connect the negative terminal of the multimeter any where in the chase( metal body of the amplifer). Then connect the positive terminal to all the output transistors emitter pin one by one . The voltage should be bellow 0.5V. If any of the emitter of the transistor shows voltage more than +/- 0.5V., then that amplifier stage is faulty. Remove the transistors and check it. if it is shot then replace with a new one.
After replacing the transistors do not power up the amplifier directly from the main. You have to put a bulb of 60 watts in serial.
You can do this easily remove the mains fuse. Put the bulb in a holder. Now you have two wire from the holder. connect one of it to the one end of the fuse holder and the other wire to the other end of the fuse holder. Why using a bulb is, if there is any further problem in the amplifier stage on which the transistors replaced, there is a possibility of the new transistor get damage. if we use a bulb in serial with its mains supply ,when any overload in the amplifier occur the bulb will drop the current, by lighting itself.
After connecting the bulb in serious power on the amplifier. watch the bulb. It should light for one or two second and go dim ,then remove the power , remove the bulb insert fuse and connect the power and check.
(If the bulb shows bright light then there is some component also faulty in the same amplifier. after removing the power you have to check again the amplifier stage of which the transistor is replaced, for any other faulty components

OK

Marantz model PM 400 yes its about 30years old. Problem volume does not respond to knob changes. Very cracklie sound. Do I need to replace the amplifier or is their a service agent on the sunshine coast...


It can be fixed by yourself. All you need is some tuner lubricant (available at Radioshack or similar store, or if nowhere can be found you can even try WD40). Pull the knob off so you can see the shaft. Spray the tuner lube onto the shaft (let gravity be your assistant). Replace knob and work it back and forth until it moves more easily than before. Test it and you should be golden.
