Question about Alesis RA-150 Amplifier

1 Answer

Hi there, I have an ALESIS RA300 AMP that has been diagnosed as having a totally corroded main power board? The electrician has been having trouble locating one to replace the old one, so I thought I would contact you guys and see if anyone can help me with what this part actually is and who I can order one from? I have absolutely NO idea about the internal organs of things with buttons and knobs and bright little lights.... : ) tnx, Cristina

ALesis doesn't make it anymore and you can buy one for about $185 online.
If you could find the board , it would be about $75-125

    I am hoping I am able to locate the right part, do you happen to know the exact name of the power board... it is still at the electricians and it would be awesome if I could find the part and take it to him and then my little AMP is back safe and sound (pun intended) in my wee studio.

    Thank you for your help petraman : )

Hello. RA300 used only in a studio environment, never pushed hard. During a mastering project we lost one side of the amp. Thanks!


The first things to check are the devices on the heatsink. They do all the work so tend to go when pushed! Remember stereo amps are just two amps put together, so at least you have a good channel (which is the same as the bad one) to do tests with say an ohmeter.

I have an elesis RA 500 it blows the slow blow fuse when i plug it in .any ideas what is wrong?


hi there,
it sounds like the internal transformer has gone.
It's not user replaceable and will require you to take to an electronics store to be repaired.

SAME THING RECENTLY HAPPEN WITH ONE OF MY BITS OF KIT ...... for heavens sake don't just keep changing the fuse time and time again.

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

Took my RA300 and Tannoy Reveal X speakers to a cellar party for halloween. No drinks were spilled or anything but it had an ipod plugged into it most of the night and the volume on the amp turned to max,...


Normally when people bring their HI-FI to a party they tend to fix up the leads to the speakers in a flimsy manner ( as it is only temp) . With the crowd mulling around these leads(wires) could very well come loose or even short out. This leads to your Final Drive ( Output Amp) to short out. It is not an expensive repair. Check your final amp & replace any shorted/blown items. To get full satisfaction the job best be handled by the local agents of the amp.

Amp cuts out after a while


My Alesis SA-300 started the cutting out when at moderate levels some months ago... Well, Radio Shack has instant gratificaion for those who have one in the neighborhood. Part number 275-249 will do the trick!
http://www.radioshack.com/product/index.jsp?productId=2062483

I replaced the Dong Woo part with the Radio Shack item and the amp is back to its old self... maybe even a little better. Loud, clean and steady.

Thanks to all you who have contributed to this thread.
