Flexwave amp fuse holder - Crate FlexWave FW15 Guitar Amp Combo, 15 Watt Single 8 Speaker

The fuse rating should be printed on the panet right by the fuse holder. If there's still a question about values, you're best bet is to contact Crate customer service.

However, if you're meaning that you keep blowing fuses and therefor think you're instaslling the wrong value, you may have a short in the amp that's casuseing the fuses to blow. In that case, it needs to go to the shop. If you're not a tech, don't poke around inside it. You can make the problem worse, or even get a nasty shock.

Contact Crate for the best info.

Solid state amps are very subject to blowing out the output transistors if speaker leads get shorted. Take it in for repair.

Hi there,I have the same problem with my flexwave 120. I opened the amp to measure several capacitors on the small effect circuit board. If one of this capaciters have internal short circuit, wich will effect the others causing effects to fail. I removed them one by one to find possible short circuit. All capacitors were ok. I think the problem is in the processor wich is to diffucult to replace. I think it's easier to replace the effects circuit board. But where do we find this board??

Hi, blowing a fuse in an amplifier is a problem that most guitarists face at one time or another. If an amp won't turn on, or it turns on for a second, then makes a popping sound and turns off, the problem is usually a blown fuse. Though a blown fuse can be a hassle, especially during a performance, it does not have to put a stop to your musical enjoyment. With a spare fuse you can be back jamming to your favorite tunes in no time flat.

Things You'll Need

Fuse.

Instructions

Turn off the amplifier and unplug it from the wall.

Locate the fuse, which is usually found at the back of the amp. The fuse will look like a small black wheel sticking out of the amp with a number and the letter V next to it. For example, 9V.

Gently turn the fuse counter-clockwise to remove it from the amp.

Discard the old fuse.

Insert the new fuse into the empty fuse slot and turn it clockwise until it is firmly in place.

Plug in the amplifier; make sure the power switch is in the off position.

Turn the amplifier on to make sure the new fuse is working properly.



Hope it helped..

Josh,

I also need schematics for this amp. How about whoever finds it first shares with the other?
Cool, Thanks,

Do you have electronics experience? Inspect the amp for broken or cold solder joints and any burned components. Check to see if the fuse blew and that the output IC's or transistors (not sure what Crate used in these) are not bad. Check your speaker wire as well.

its a crate. 60% of all crate amplifiers go back on defects. take the top screws out and slide out the chasis, look at the fuse and determine if its toast. if the fuse is good, get a new amp. if the fuse is bad replace it and you should be good. the circuit board will have the correct fuse to be used printed on the board.

Hi

Go to www.ezrepair.ca and send it to us.
We will diagnose your unit for free and give you an estimate in a 48H maximum period.

you have either a failing fuse or a failing power transformer. take out the screws on the top of the amp, leave the handle in tact and pull out the chasis. look at your fuse to see if it is in its holder correctly, and see if the fuse is burnt. the correct fuse values will be printed on the circuit board. if the fuse looks good then, it may be the power tranny going south.
