    inserting fuse and checking any short between the line input : multimeter show 0.5 ohm from the input plug measurement. But this board connect to other load with socket more than one and also to transformer. (note: refer to AU-X1111 detail http://amp8.com/sansui/x-xx/x-xx.htm) for our information.

    Question:

    1) it's normal 0.5 ohm?

    2) Please advise? next step

    3) Can I POWER UP 110VAC supply test?

    4) Can you help to get service manual pdf. file or ...other manual detail?

    Good day.
    Additional note: The fuse is slow blow type. TQ
    After purchase the fuse . I only can test on next week weekend . Will update you later.
    However the manual still can't get ... can you help?

Have you tried this link for the manual?

http://www.hifiengine.com/manuals/sansui.shtml

Try another fuse. That one may have been over worked, if you have the same problem again, check your capacitor and resistor resistance and voltages. Chances are one is bad.

    I believe you should get 11 to 30 ohms and 5 volts of power, I will do some searching on that to see if my theory is correct.

    So far the only one I have found is not in english. It is here:http://amp8.com/sansui/x-xx/x-xx.htm
    You could always try and highlight the words and use google translator or something similar. I will continue to search for an English Manual.

    Try this one. I think this is it:

Remove the output voltage and replace fuse to check. If possible load in series with a 100 watt lamp. If short is present the lamp will light up. If with the transformer, check after disconnecting the secondary. is still on load check if the surge protector is short or if with transformer if the primary has shorted.
The easy way out is to check for the short with a multimeter, you can confirm a short very easily by inserting fuse and checking for short into the line input , disconnecting as before to confirm.

How best to fault find and repair my Wersie Omega DX10 organs internal Amplifier


Look for filter caps with domed tops. Replace all of them. A shorted diode in the power supply will do it too. Shorted Output transistors will burn a fuse too.

I shorted out the speaker wire going to sub and now the amp doesnot work


You have probably blown the internal power supply fuses in your amp or the speaker fuse in the amp. The chances of blowing your sub are slim.

The internal fuses can sometimes be hard to find. They aren't usually intended for the user to change. DO NOT replace them with higher amperage fuses if they blow after you replace them as there has been severe damage caused to the circuitry. Also, don't replace them with higher amperage fuses because you think that this will let you get more power out of the amplifier. This won't work, and you will end up blowing your expensive output devices.

I have technics A700 MKJ amplifier, the small internal fuse keeps blowing. Can anyone please help?


Hi
did you check if the fuse is slow blow or fast blow and if it has the the same current rate?
ex: 3.14 A
anyway if the amplifier is consuming a higher load that means there are capacitors to be changed.
more information would also gives better idea of the problem.
Hope this helps.

My bass amplifier requires a ceramic fuse T10H250V. Where can I find one exactly like it?


hi,

Fuse breaks when it has succeeded in limiting further damage.


Check for other possible shorted electrical and electronic

components.


• Could be drive transistor , output transistor or both on the main amp.

But check for power supply and in the preamps also.


• Measure supply voltages,

• Check DC offset voltage

• Check idling current (main amp)

Isolate , and trace afterwards.

The power supply of computer can run the car amplifier?


probably not if it is high wattage amplifier

PC power supplies dont have enough amperage to run an amplifier

it is 12 volts but only a few amps

voltage is like turing on water in your sink amperage is like how hard you turn the water on you wont have enough 'flow' from a PC powersupply - sorry

good idea though!

if it is very low power amplifier you might be able to get it running

try it worst thing that will happen is that the fuse in the power supply will blow

Amplifier turns on green, then red. I opened the housing and found a burnt black square item with three soldered pins onto the board. Note, there are many of these pieces lining both sides of the board.


That would be the MosFET's used in the Power supply or in the Output channel stages. More than likely its the output ones, the power supply ones usually blow the fuse as soon as power is hooked up. The RED led comes on to notify you that there is a problem with some part of the amp. In this case it could be DC on Speaker ouputs or Power supply voltage mismatch. It can usually be repaired depending on if the PCB was dammaged or not. the parts arent expensive ($3 - 7 a peice inline)

Hi im in Argentina and i accidentally pluged in my amp without an adapter now it doesnt work what needs to be fixd?


The power supply is blown. Argentina is 220V I believe. I have never seen a power supply schematic for this however being that it is low power it is a linear supply not switching. Either the rectifier diodes are blown out or possibly the output capacitors are blow due to approx double voltage. If you try this yourself be careful otherwise get a new amp. Good Luck

Ground zero amplifier overheating and going into protect.


Since you changed the amperage of the fuses and the cable, you allowed the internal problems of the
amplifier to get worse than they were before the original fuses started blowing.

A fuse is a safety instrument that blows instead of your amplifier.

The problem is NOT the fuses frequently blowing, as such events warn you of internal problems with
the amplifier which you should have had serviced at the time to prevent them getting worse.

It is very much like the persons who replace the fuses in their household wiring with pennies, to prevent
frequent fuse replacement only to have their house burn down from overloaded circuitry.

Service your amplifier immediately.

Revert to the original amperage on all fuses in your vehicle to prevent a car fire.

Trying to power a amp with 16 volts. possible?


Golf carts do not have a charging system. If you are going to use battery power only, why not just add (1) 12V car battery instead of (2) 8V??

MA Audio runs (ran) their bench tests @ 17V. All the power ratings advertized are at 17V.

The power supply for the hk4000D is unregulated. So the more voltage = more power.. 8V-16VDC.

  • RMS Power @ 14.4V
    • 1800W x 1 @ 4 Ohm
    • 3600W x 1 @ 2 Ohm
  • RMS Power @ 17.0V
    • 2000W @ 4 Ohm
    • 4000W @ 2 Ohm
    More input voltage means the amplifier will have to work less hard to make power.
    Don't expect the amplifier to work for very long however. the current drain on a class D amplifier is huge. There are no on-board fuses protecting the power supplies, so be sure to have at lease a 150A power line fuse.
    With 150A current draw - even with the amplifier at 1/2 gain - expect to get 10.6 minutes of listening time from your 16 volts before recharging - also note, the amplifier MUST see 8V to turn on, there is a built-in voltage sensor that will shut down the amplifier if voltage is too low.
