Question about Alesis RA-150 Amplifier

1 Answer

I bought an Alesis RA-150 used on ebay. It started having a problem shortly after I got it and the problem it getting progressively worse. Each channel will intermittenly cut out suddenly (not at the same time), but if I turn the volume knob back and forth quickly a few times it will be okay. Then it may be fine for an hour or a day and then it will do it again. I appreciate your help with how to fix this.

Sounds like the volume controls are dirty. You can try just working the volume controls up and down (amp off) that sometimes helps. If they are really dirty, you will either have to get some cleaner made for switches and pots (a spray can with the little tube) or take it to a reputable stereo or PA repair shop and have them fix it for you.

Not powering up at all


OK one thing at time first take cover off unit then check fuse if its blown there is a short do not replace fuse yet then locate bridge rectifier
check it for short if it is unsold-er and replace it then locate output transistors and check all of them for short. if one of the devices that i told you to check is bad then when you replace it then replace fuse and try powering up unit. be sure to replace all shorted parts before replacing fuse and powering it up.

Check for a stereo/ mono switch in the front or back, and make sure it wasn't accidentally switched in the wrong position. Also check and make sure the wires are not crossing each other causing a short.

Alesis RA 500 makes a "clicking" sound and no more sound. later it will "click" on again


Clicking sound is a protection relay. This means one of the power amp sections have failed. Or that your speakers connections are faulty

Audio problems with Alesis RA-150


on bridge mode the speaker impedance should be 8ohms, less than this clipping will happen. try bridging two 4 ohms in series.   
if this happens without speaker connected, u have a power amp section that is trying to draw more power than it can handle. 
as for the second check connections first, otherwise i suspect u have a defective power amp for the right channel.

The switch in the front which turns on the amplifier broke. I took off the switch with the two white and yellow wires. Not knowing i couldnt find a compatible switch..... help......


Try Digikey.com and Mouser.com.

If that centered oval thing is the power switch, it is LIKELY a special and you MAY have to go to Alesis to get a replacement... I hate it when they use specials...

The other thing is to see if the actual switch or mechanism MIGHT be the same as a part you can get via one of the sites mentioned above.

Alesis RS300 Reference Amplifier Channel malfunction...


You say "it seems like". Do you mean to say it is intermitent, or did it start cutting out and then finally fail? If that is the case I would look first to replacing the relay in contention in this thread.

It's a cheap fix and will eliminate one potential cause. The Radio Shack part is widely available.

My RS-300 had started dropping the left channel, but occasionally both. It is possible that the relay has failed on one side and thus you have a dead channel...I did the fix and am now quite happy with the amp
