This sounds like the main rectifier diode/bridge is shorted. If you can rpovide the make and model, I may be able to give you more details.

Thanks,
Dan

On the small Fender 15G/15R amps, if the power amplifier IC is bad it will immediately blow the fuse when powered. To check the the IC you have to remove it from the chassis and measure the resistance between two of its three legs. You need to find a schematic for your amp online and measure at the test points with a meter as a starting point.

Amp blow fuses immediately when power is switched on


There could be so many things wrong with it, but personally I find the most likely problem is the power supply.

PA Amplifier blows fuses


The fuse is blowing due to an overload. It's often and very likely caused by a transistor or ic that has gone short. The main culprits are the power transistors of the amp or whatever is on the big heat sink. Transistors will show the fault when you connect an ohmmeter to the terminals. It will be just like you have touched the test prods together! I don't think in your case it will be in the power supply. It's often caused by speaker cables that touch together.

My technics integrated amplifier su-v85a blows the fuse everytime i turn it on.what can be the problem?


Fuses blow when there is an overload. Often caused by a short-circuted semi-conductor. I would go straight to the main amp board and suspect the devices on the heat sink.

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.

Fuse type for onkyo a-9555


The main power fuse for most amplifiers is a fast blow, 125 volt fuse for the US and a 250v fuse in countries with 220v. This unit is 125 watt so the main fuse should be 2 amps or so. The correct fuse size is written on the circuit board next to where the internal fuse was located.

Need fuses for samson amp


The manual recommends 4 Amp Slow blow for 115 volt operation or 2 Amp Slow blow for 230 Volt operation for the 201a.

For the 260 Amp manual shows 10 Amp normal for 115 volt operation and 5 Amp nomal for 230 volt operation.

There could be a short in the rectifier diodes or in the transformer itself. Can you take some measurements inside the unit?

Let me know.

Amp won't put out sound


Hi there,

A lot of Amps come with fuses as a safety mechanism so you don't blow the speaker and/or internal components in the case of a power surge etc. Check for a blown fuse. Sometimes they have a fuse holder in the back of the amp and it is labelled "fuse" which cetainly makes it easier to find. Hope this works and helps.
