When a piece of equipment causes a fuse to blow or a breaker to trip, it normally means something in the equipment's circuit was shorted. Either because of heat, moisture, a loose screw, loose wire, loose part, a bug, etc. For safety reasons, don't plug it back in and take it to a repair shop.

Hope this helps!

Wayne, There's a time to take the amp to a pro shop andf get it done right. It' saves time and headaches, and also keeps you from inadvertantly smoking other parts or yourself. Now is that time.

Since you have tried all external possibilities, this will require troubleshooting. If you are not adept in electronics, you best take this to a shop familiar with this model.

If I were troublleshooting this, I would suspect the power amp transistors or connections to them might be bad, but the testing would likely use an oscilloscope to trace the signals in an expedient manner..

One schematic for Crate I found uses darlington transistors TIP142 and TIP147.

I have a Crate GT 15, not getting anything to the speaker when I plug in.


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.

It will not work what colud be wrong


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.

Buzzes and feedback


Make sure the "ground lift" option is used on the direct box.

DO NOT UNDER ANY CIRCUMSTANCES use a headphone output jack as the output of this unit. The headphone jack is for HEADPHONES that have no return to ground. Use of this as drive to a sound board is sure to cause problems and in some cases can fry these amps due to the circuitry.

The cable used to go to the direct box should be very short and high quality.

You should source the power for this unit from the SAME source and receptacle as your sound board if at all possible.

did you change out the fuse? could be a tranny going south. if you change the fuse and you still get no power, then you have a fried power transformer. they are relatively easy to replace. look on ebay . get the numbers off of the existing one and start web searching. something will come up. if not email me on my contacts tab in my website yostamplifier.com we can troubleshoot. you should see the custom blue voodoo i built and gave to my little brother.

Plugging line level into my crate TX15. all inputs sound distort


guitar amps are all set to a low Z resistance configuration. wich are made for guitar only. make sure you are using the right cables.
you need sheilded guitar cable not unshielded speaker cable in many cases these cables look exactly the same. look at your cable look for the words speaker or instrument. you need the instrument cable. if you still have that problem. then you may just not be satisfied with the quality of the amp it self.

Crate tube amp will not power up but cooling fan tries to run


Yes.
Are you saying that the only indication that it is running at all is that the fans are running? So the tubes don't light up? No indicators on the front of the amp?
Power supplies that provide multiple voltages, which your amp has, can provide some of the voltages while having a problem that prevents them from providing others, all while not blowing a fuse. If you are not confident in your ability to work on a piece of electronic equipment that has 120VAC coming in and at least 175VDC or more present inside it, bring it to a service center.
The good news is that it is probably not horribly serious. Problems like this can almost always be repaired in a cost effective manner.
