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.

Crate club 50 15 inch speaker developes a tremolo sound mildly after tubes warm up


I am Going to do a little guessing. I am not a speaker pro by no means. but i have been using them my whole life.. as a fellow musician. i've run into this half a dozen times. each was different. so you say tremelo effect. could you describe as a harmonic vibration as well." if so look for anything (start w/ the speaker and work your way out) your looking for things like a loose nut or bolt. the speaker should not wobble or move at all. look for separation in the speaker cone and diaphram. then work your way out.. your looking for anything can potentially rattle, and usually against something . check around the tube mount, be careful. dont want it getting broke or you electrified.either that, or turn your effects off. just kidding. gtood luck

It is likely that there is a failure of one of the amps in the unit. It could be a cracked circuit board, bad solder, bad volume control, or a bad compnent in the power amp section for one side. HOWEVER something does NOT compute here as you can't connect more than one speaker to a 15 Watt Crate amp... Maybe you have two of these amps.

I bought a Crate CR212 new in 84 It came with celestians they are


I can't be sure for the result at your area, but I have to tell you that whenever I rebuild speakers at technicians in Greece (that's my country), the results were not very good. They always worked but after some working period started to make strange noices. Especially if you are a mucisian and the amplifier is yourself, replace them.

In case of a problem or clarification, don't hesitate to post me a reply.

Dirty high switch on a Crate practice amp


NEVER use switch cleaner such as DeOxit on pots !!!!!

I have used CRC226 available at Home Depot electrical dept.

I SUSPECT that the resistance element in that pot is cracked. This is common if the knob sustained a hit. Replacing the pot is the only cure if the element is cracked.

Reviewing the schematic, ALL audio passes through the wiper on the HIGH tone pots. If the wiper is intermittent, so will be the sound.

If your unit is solid state amp, the pot looks like a 10K ohm LINEAR taper.
If you have a tube type, then the pot is a 250K ohm LINEAR.

Note that the other tone pots in the units are AUDIO tapers, but the high is a linear taper.

Get repair parts from either DigiKey.com or Mouser.com

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.

Hi

The problem is with the amplifier itself. Crackling is usually capacitor related and you will need to have the amp checked over to properly identify the cause.

Some amps are also prone to pick up static from other electrical items which can also cause these problems. I had a crackling issue with an old Crate amp of mine which turned out it was due to being too near a computer/monitor so it is worth eliminating these things as a possible cause before having the amp checked.

Hope this helps. Thanks for using FixYa.

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.
