Is the right output transistor part number the same as the left output transistor.


Should be provided you only have a single transistor in the output power stage. If you have a pair of transistors in push pull arrangement, then those two units for that one individual channel will be different.

Behringer troubleshooting


Check instrument cable, cable jack on guitar, cable jack on pedal. If pedal has gigged much, the last is most probable

No sound from amp. Turns on, but seems to be clipping out and is popping. Any troubleshooting advice?


check the connector where your instrument cable comes in. Make sure you are getting a good connection. Unfortunately, there is likely a bigger problem.

Where is the serial number on a crate amplifier


Real basic owners manual is here:
http://www.crateamps.com/pdf/manuals/CA6110DG_OM.pdf

Look at the chassis, or pull a part number off the original speaker to match speaker and back cross reference to the amp versions that used it. The OM is at least good enough with the block diagram to allow it to be serviced easily enough.

Acx1800 no bass very small volume, brand new amp.how do i put my speakers in phase?


If you are sure that the input device (I'm assuming electro-acoustic guitar) is working properly then it sounds like a clear case for return to the vendor! If it is brand new then don't even try to repair it. The phase buttons on the guitar channel are to help reduce feedback by putting the body of the guitar out of phase with the speakers. The speakers should all be in phase with each other though.

Low volume for a 180 watt amp, does this amp have one 180 watt power amp or two 90 watt power amps?


If there are stereo effects , like chours and delay it more than likely has 2 90watt amps

BEHRINGER AM400, I seem to be getting what appears to be a hissing sound coming from my brand new acoustic modeler pedal. If I turn the "attack" level right down it seems to reduce the problem....


First of all you should try to use another guitar - if the problem is still there try using different batteries or another power supply unit and finally a different amplifier. If none of these actions lead to success i would send it back if i were you.

When you buy equipment you should always test it at the shop to avoid such problems!

Berhinger acx 1000, power on, no sound amp not working, everything lights up on display but no sound or amplification


Just had the baby brother (ACX450) with this problem...opened the amp... screws from sides and or top (including 2 hidden under handle covers).

The power cable from the power transformer had come off the connector on the circuit board in spite of goo they had put on it. Put connector back on and secured the cable and works perfect,

Since your display lights, yours is likely a different problem. I have also seen similar ones that the cable to the speaker had been pulled off its connection on the circuit board, rendering no sound. See if you have sound at headphone jack. and if none, how about the preamp output jack? Note you will only hear the left side using earphones as these jacks are monaural.
