I have the Zektor HDS4 Component switcher. The power adapter has a short in the wire just before the plug. Zektor sent me a replacement but it's got the same problem (due to how it was bent in packaging I guess). I've decided to buy my own but radioshack doesn't have one that is Output: 9VDC 500mA. Can someone suggest were I can order one matching the specs below?

Class 2 transformer
Input: 120V 60hz 12W
Output: 9VDC 500mA
2.1mm DC coax plug (center positive)


I'm no expert on this stuff so I'm a little unsure of which to get. I though of maybe a 9VDC adapter with a higher mA rating but wasn't sure it's safe. Since I'm paralized from neck down I can't solder a new plug end on the bad adapter. And don't know anybody who can. Any help is appreciated.

Universal transformers that can handle 9v and 500ma are pretty common, so I would expect that there are alot of choices that you can use.

Universal transformers come with a selection of tips that you can use, that cover most (if not all) plug sizes, plus the tips are usually reversable (for positive or negative tips).

Thx Robman. I think I found what I needed at Parts Express #120-1055. Then after doing so a friend said he could check the cord with a meter. Turns out the cord is fine and the unit must have a faulty PC board. Zektor is shipping me a replacement unit out tomorrow at no cost with a postage paid return shipping label for the faulty unit. Thats good customer service considering I've had it since February. Smile

Just for future reference... you can use a power supply with any current (A or mA) rating at, or above, what's required. So, you can use a 500mA, 600mA, 1A, 2A, 5000A, 4.71gA, power supply, as long as it's supplying 9V of electro motive force. Smile

Parts Express, MCM Electronics, and uh...er... damn, forgot one other place I know of that has a boatload of power supplies.

Oh, hosfelt! That's it.

Radio Shack is probably a lot more convenient, and they will definitely have what you need...

While this may seem true, it is only true in the case of well regulated supplies. For example, a simple 9volt 5 amp supply might produce as much as 15 volts when only loaded at 1/2 amp. You only need to be close, just don't get carried away.
