Replacement for an akai 10.5v 300ma adapter

I picked up an akai u40 riff-o-matic with no power cord. I knew that 10.5v was odd but i didn't think it would be this hard to find a suitable replacement.

The voltage won't be that critical... 10 to 11 will work. Just make sure the type (AC or DC) matches AND the polarity for the DC units.
Often these can be found at thrift stores.

I have noise occasionally from my headrush 2 can i have someone modify it seems to click on and off at times

Most common cause is loss of power due to poor connection. These are usually turned on by plugging in the inout cable and a worn plug from the guitar may be intermittent. The sleeve of the inserted plug usually turns on the battery or the adapter power to the unit. Adapter plugs are notorious for poor connections. Another common problem is broken solder at the external jacks into these as cords get yanked and stepped on resulting in force on the jacks breaking the solder. A momentary power loss will trigger the unit off.

if you're using an adaptor other than the original zoom, make sure it's 300mA or more and try switching the polarity.

I was playing away with my EZ-200 keyboard and before I knew it, the power went off. When I tried to switch it on again, the light came on for a second then went off again. I haven't been able to play...

It is UNCLEAR if the utility power went off or the keyboard just turned off. Assuming the latter, things to check are that the power cord is seated. They chronically come part way out. Verify power from adapter is good. If by chance you are running this on batteries, the action you describe is what hapens when batteries are exhausted. They recover enough for a brief flash and that is it. Also if using an adapter, it may store a little energy and if your wall plug happens to lose power the action would be typical. Plug a lamp into outlet to make sure it is hot.

I have an allen and heath Xone 22 Mixer. Its great, except due to the lack of a power switch I pulled the ac adapter/power cord out too many times and now it has a really bad, loose connection. It works,...

Usually the connector that is board mounted is the problem. I would OPEN the unit as there may just be broken solder at the connector inside. If the connector requires replacement, find one at by searching for "power connector coaxial".

Hint: In the future install one of those little lamp switches that are in a little plastic box with knurled knob sticking out the sides. ONLY break ONE wire from the adapter to avoid getting the connections reversed. Since the wires are smaller than lamp cord, tack solder the wires to the piercing points of the switch .

Using generic battery adaptor on Digital recorder

Others have had problems doing so. I would get one specifically for the unit. One person got an adapter with an "S" suffix and that DID NOT WORK.

Get the exact replacement for this particular device as called for in your manual.
