Chosen Solution

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!

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 http://www.bematech.com/support/download… 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. – Tai

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.
