Ashdown perfect ten bass combo. Just stopped working.

On the larger models, there is a small door directly beneath the power plug. On this model, the manual does not show a door but, the fuse may be there under the plastic. I'm really not sure. Removing the 2 screws on each side may allow the plug to be pulled out, unless there is a door.

Any good electric part shop should stock the fuse. I assume the 10H means 10 amps and the last bit 250 volts.

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.

If you mean the light in the meter, those can be hard to replace and mosts shops would replace the meter itself which would up the cost. It is probably a 12 or 14 volt bulb(s). Look at the back of the meter and see if there is a removable socket to get at the bulb... if not, then the bulb(s) is internal and probably a soldered in grain of wheat bulb(s). If you have never worked on meters before it takes GREAT care to keep contamination out when working on them. I would certainly not pay $85 to have bulbs replaced... use an external lamp if you really need to seee the meter... one of the little LED ones would work.

Strange request... power transformers rarely go out and this one seems to be very well protected by fuses. I would verify that the transformer is actually bad before trying to get another. You would likely have to go to the original manufacturer at great expense. There is also the question of why it would go out. I see rectifiers and filter caps that OFTEN are the problem as well as the power amp itself.

The fuse blew because of excess current. The cause of the excess current is either excess volume, a short in the speaker, OR the amp has failed and is shorted to one of the power rails internally and is driving DC current out.

Replace the fuse and use a meter to check the output voltage with NO speaker connected. It should be under 1/2 volt period. If it is, then check the resistance of the speaker. The DC resistance should be a little less than the rated impedance. Otherwise if the amp is kicking out a higher voltage or blows the fuse again, have the amp repaired.

okay , well you need to make sure all your conections are in the right spots, and that your IN LINE FUSE, between your amp and battery, the big glass one is not burnt, just take a look at the metal piece inside , if its a sold metal piece its good, if its burnt in half like a broken bridge it needs to be replaced. the next thing is the fuse on your amp, you need to make sure it is not burnt also. Check your remote that it is hooked up to the right wire. then check that your sub/speaker wires are connected properly and secure. YOUR GROUND WIRE IS HUGE HERE also. MAKE SURE IT IS GROUNDED TO A GOOD SPOT, YOU MAY HAVE TO MOVE IT AROUND A FEW TIMES TO FIND A GOOD GROUND!!!! if you check all of these things, it should work fine.. you can fiddle with your amp and bass settings levels. turn em up so when it works you know it, but not too much you dont wanna blow nothing :)

one of the subs are blown

can you use headphones? if so do they sound normal. probably have bad filter caps. 2200uf caps big ones, go bad and lose their capacitance and cant process the low end notes, sounds like a motorboat or ******* out. speaker may have issues as well. get the caps from mouser.com and careful of stored voltage on the capacitors it is deadly....... those caps are less than 2 bucks each.

What main fuses? Fuses in the car electrical system? If so, your amp is too powerful to run through the cars electrical system, you should get a heavy guage wore ran straight from the battery, with its own dedicated fuse placed in-line, ad close to the battery as possible. Wait, is this a bass guitar combo??? Open it up, if there's wax coming from the power supply, thats prolly the culprit. Check for any obviously blown resistors or any short circuits. But most likely, its not gonna be user-servicable.
