Aragon Audio Players & Recorders - Recent Questions, Troubleshooting & Support

The Aragon 3002 and 3005 are power amplifiers that are no longer in production. Here are some general guidelines for testing, bias/DC adjustments, and levels for power amplifiers: Testing:

1. Check that the amplifier is receiving power and that the power switch is turned on.
2. Check that the speaker connections are secure and the speakers are working properly.
3. Connect a source such as a CD player or turntable to the amplifier's inputs.
4. Set the volume level to minimum and gradually increase the volume to the desired level.

Bias/DC adjustments:

1. Bias and DC adjustments are typically performed by a qualified technician using specialized equipment.
2. Improper adjustments can damage the amplifier or speakers, so it is important to have a professional perform these adjustments.

Levels:

1. Levels refer to the volume of the amplifier's output.
2. Adjust the level to match the desired listening volume, keeping in mind that excessive volume can damage speakers and harm hearing.
3. Use caution when adjusting levels, as sudden increases in volume can cause hearing damage or damage to equipment.

Fuses blow when there is an overload caused by a short circuit. If the speaker you connect up to the amp causes a short. There is either a shorted part in the speaker or the wires to it are touching at some point. Assuming you can sort out the speaker issue and connecting a good speaker with good wiring and it still causes a short and blows a fuse. Then it's likely the output device(s) in the right channel have developed a short themselves. Perhaps as a result of being connected to faulty wiring or speakers.

I can tell you what's wrong with it. Fuses blow when there's an overload. The cause being either the power supply or a shorted transistor on the main amp. I can't tell you were to take it though since I have never heard of the make. Any repair person who repairs Audio amps should be able to fix it, depending if they can get hold of the parts.

The reason they spark is that there is still power and load when you put the fuse in instead of putting the fuse in put a mains light bulb with its terminals onto the fuse terminals and this will safely discharge your capacitors and making sure that your power is off put your fuse in there should be no spark and switch on if the fuse still blows you have faulty gear

Chec whether balance control is adusted properly. Check the speaker connected to left channel. Check the power amplifier circuit of the left channel [a skilled work indeed]

Yeah, using a common search engine, which is always a good place to start a quest before asking Experts.

"Aragon 28K manual" turns it up.

Have you the remains of the fuse, or was it just not in place when you got it?
The reason I ask is that the amp's fuse doesn't have much to do with the voltage of the mains supply (in your case a 250V fuse will cover it). It goes on the load in Amps or Milli-amps. Shown as A or MA. If you have the old fuse you might be able to see it on the case of the fuse. It might say 1.5A or 500ma etc. Also there are two main types of fuse, known as fast and slow blow fuses. Again if you have the old fuse the remains of a coil inside will mean it's a slow type. The other type is just a wire. However you can fit a fast blow for a slow one. If the fuse blows again it will be a fault that causes it.
If you have no fuse left at all you will either need to find someone who has the same amp and to tell you what it is, or the circuit diagram for the amp. Sometimes it's even printed on the PC board!

Find someone not afraid of screwdrivers. UNPLUG the unit from everything and remove the cabinet screws ( most likely a few on the sides and 2 or 3 in back. Put the screws in a ziplock or something so's your dont loose them. Remove said CD and put screws back.

What does Aragon suggest?

I'm in Vermont so shipping might cost you a bit.

If it had dual power supplies, the unit would still have sound on one channel

Take the scew out and take it to a hardware store to get an allen set screw put that in and tighten with allen wrench. BIG RED

If the display is working, you have audio. Check your amplifier. 1300Watt adaptor ... This unit draws a very low power and that is not needed.

1. Power Off: Turn off the device.
2. Jumper Configuration: Locate the jumper labeled "S16" on the device. Initially, it should be connected to pins 2 and 3.
3. Power On (Alarm+All LEDs Flashing): Turn the device back on. You'll see the alarm LED and all other LEDs flashing.
4. Power Off Again: Turn off the device once more.
5. Jumper Adjustment: Change the jumper configuration from pins 2 and 3 to pins 1 and 2.
6. Finished: Your Porpo YH-2000 is now set to the desired angular unit mode.

If you encounter any issues, you can press the reset switch on the back of the device to reinitialize it.

this model SA rather than SC seems to be a Middle East model. The SC version doesn't have DAB. https://www.google.com/search?q=panasonic+sa-pm250+instruction+manual ..
