Theres power but no sound, check the cable connections to the speaker, there might be disturbances during vibration that got the cable disconnected or loose, if connections are fine than most likely you have a defective sound IC, need a technician to Identify the IC for you to replace it and test the item. cheers.

Wont power on


I would check the power cord and switch first. I have replaced lots of these and the switches get dirty over time from drying out and/or wearing out. Make sure the fuse is good.

While playing, the power cord was accidentally pulled out. When plugged back in, the amp cuts on, but there is no sound and the led lights for peak and tone selection flash.


You have probably blown a tube. This amp has one 12ax7 and one 12au7 in the vintage preamp. You can try replacing the preamp tubes, but it can be quite dangerous if you don't know what you're doing!

I have no sound. Headphone jack is working. Speaker is not. Need help troubleshooting.


With no leads connected to speaker, use an ohmmeter to check resistance of speaker. If NOT less than 10 ohms, you be replacing the speaker. Also look for loose speaker wires. More than that and is will require repair in the shop.

Ampeg BA600 115 combo power cuts in and out!


Broken cable jacks are most common problem. Cracked circuit boards and bad soldering is second on the list.

The CD input on my Ampeg BA 115 works, but the 0db and -15db inputs don't. This happened immediately after using the CD input. Quick fix, or repair shop? Thanks.


Hello,

Sounds like a repair shop job to me. Inputs on a amp have resistance thus there must be a issue inside hence 0DB to 15DB if you go higher well that input thus would not work anymore.

Repair shop would be your best bet for this amplifier. Quick Fix would be unplug it and plug it back in and praying it resets but that won't happen.

hope this was of some help, if not I am sure others will chime in with there 0.2 cents.

My ampeg BA115HP is dead. I suppose it is the fuse. Where is the fuse located?


it's the black thing sticking out of the circuit panel on the back of the amp

Brand New Ampeg Ba 600 210. Only Used durin 2 shows. Sound is awesome. Go to use it this weekend and absolutely no sound at all coming through the speakers. Compression, eq and Everything else working when...


Another person posting on here I suggested opening his unit and he had blown speakers. I think these that are DOA after previous use may be blown during the previous shutdown of the amp driving them and those with built in amps are blown when mixer is powered down putting out a large pulse. Hopefull the amp is blown rather than the speakers... cheaper to repair. Open and check for a fuse, but dont' replace it until you find out the cause of it blowing as additional damage can occur.

NO SOUND


Blown soeaker or amp. Only way to analyze is to open it aand do testing. First plug headphones into the 1/4 inch line output jack and see if anything comes through... it will only be in one ear as the ouptu is not a stereo output... If it comes to there, then the preamp and line driver is working, leaving the speaker and power amp suspect. If nothing ocmes out, I suspect the power SUPPLY might have failed.
