Power Adapter ISSUES

Dare I say that if you don't have a multimeter, then you might have trouble getting the pinout right. I somewhat doubt Dick Smith will carry a centre tapped power supply. Ask whoever you sent it to to check if the power supply is outputting the proper 16.8 volts. I am guessing that between one of the pins and each of the other two, you will get 16.8 volts and between the other two pins you will get either 33.6 volts or 0 volts depending on how it is wired. The more I hear, the more I think that it is something internal.
 
DSE along with Jaycar and Altronics all stock multi tap transformers but the question remains as to what the fault is. I wouldn’t even worry about trying to find a new transformer when you don’t yet know whether the fault is in the power supply or in the desk. Post again once your friend has isolated the problem.
 
They will sell the transformers but not plugpacks. Just got out the Jaycar catalogue and the closest that they have is a 15-0-15 transformer. Altronics are much the same. DSE has a smaller range the either of the other two. Wait until you hear what your friend has to say abut it. Then we can consider ways to replace the transformer IF that is the problem.
 
ok i have the results of the intesive psu search

apparently the power pack was faulty and is out of production so im going to have to throw the desk away and buy a new one (sob)

Before you throw away the board I would get a transformer specialist to look at it. They will be able to test it to see if the coils are damaged. If they are they should be able to rewind it. Get a quote to see if the cost of a rewound transformer vs a new board makes it worthwhile.

I don’t want to sound rude, but I would have expected an “electronics expert” to have given you a bit more advice than to simply throw it away.

You should be able to find a transformer that will suit this supply. The idea of having it custom would is also a viable option for you. Another thing is to look at the power supply kits that DSE, Jaycar and Altronics have for their own amplifiers. If I remember correctly, some of these are within the power range you are looking for.

ADVISE: I would try to find a local audio service technician to look at it for you. They might have a second hand transformer or can tell you who best to source one from.

In most cases, the power needed is variable to a certain degree and you might find that a 15V supply or a 12V supply might work. However, you would need to have someone qualified to look at the desk and advise you on this.

Otherwise, if you are going to toss it, you can toss it in my direction!
 
I wouldn't spend much time or energy on this, I would just get a new board at this level of equipment we are taking here.

please help me it has become an item that i tresure

The item has significance to the owner and so he wants some help to make it work again, so we are providing the help. I'm sure that if the original poster had not wanted to make it work again, he would not have asked.
 
emailed some people and found out the following infomation to part i require is
Phonic part number:353-22009-000-0. (if that helps anyone) it will cost me $80 plus shipping of course i could just walk into my local sound store and buy a small two channel phonic desk for only $50

WORK THAT OUT!
 
Ahem, I am entitled to my opinion. And it looks like the OP is buying a new board anyway!
