Harman Kardon SoundStick power supply and pin outs?

I have a Harman Kardon SoundStick without power supply. Looks like Harman Kardon sells the replacement power supply, but I want to know the pin outs so that I may be able to power it up with power supplies I have.

Can someone tell me the pin outs of the connector of power supply?

If you have one, please!

There were several versions of the HK SoundSticks with different power supplies. The first ones plugged into the sound port and later went to USB. Which ones do you have?

by

It says "SoundSticks", has a USB. It also says 16V, 1.5A.

I noticed you never got an answer to this. Are you still having this problem?'

by

It's still sitting in my attic, and would like to power it up.

I think I found the answer, in two ways.

I got my hands on the actual power supply, and confirmed the pin out.

Also, the plug is Hosiden TCP8927-53, Kycon KPP-3P, as found in Wikipedia's DC_Connector.

You can find the pin out in

I confirmed that the pin out in above matches with the actual power supply, so I am good to go.

I can probably get the Kycon KPPX-3P from Mouser, and a 16V power supply, which I plan to use a laptop power supply I can get cheap.

I built a replacement power supply for a Harman Kardon SoundStick by finding a laptop supply of approximately 35W on eBay. I bought an IBM Lenovo ThinkPad 16V 2.2A Laptop AC Power Supply Charger 85G6734 for £6.99 as it seemed about right and was a fair price (though then had to additionally by a clover style power chord for another £3 so check on eBay that you're buying the whole thing or that you have a power chord that is the same style).

I cut the end off of the power supply behind the choke as this was getting in the way.

Next fit a new plug - the Maplin 3 pin power DIN plug assembly (their code: N83KT £1.49) is the one you want. It's a bit complicated to assemble (and quite amazing for less than £2) but after a few tries it fits together well. There is some soldering required so you'll need to buy or borrow an iron and solder. I hadn't done any soldering for over 20 years - if you concentrate on melting the solder onto the joint to form a bond and don't worry about doing anything else you should be fine.

The pin connections are as shown here: http://www.bematech.com/support/download.... On the Lenovo power supply the sheathed centre wire is the +ve (pin B) and the outer stranded wire the -ve (pin A).

Good luck.
