    Greetings everyone,

    I have a Philips Sound Selector ST300 (a sound machine), but cannot find the power adaptor cord for it. According to the information on the device, it's 12.0V and 500mA and accepts a DC plug. I'm completely clueless. Any ideas on what type of power adaptor cord I need to purchase?

    Thanks in advance,

    I know this post is very old now, but to assist others who may read this... goto ebay and type in the search box '12v dc 500mA power supply' you should find many on there which are suitable.

    The voltage needs to be very close to 12 volts (eg: 11.5v or 12.5v is ok). The amperage can be higher than 500mA... you could use 800mA or even 1A, but do not use a lower mA rating (eg 300mA) as it will get very hot in use and probably burn out very quickly.

    take those stats to a electrical hardware store. Not best buy or anyone like that. Take somewhere that sells caps resistors leds. Raw materials and im sure they could help you alot better depending on your location.

    Radio shack used to carry them, maybe still does.
    Make sure you've got your polarity right on that DC plug.
    (They're made both ways, internal barrel positive, or negative. Make sure you've got
    the right one)

    The only reason I replied to this old post, is to help others that may find this post when looking for a solution themselves... hence my opening line "I know this post is very old now, but to assist others who may read this..."

    How many times have I been looking for answers on forums only to find that the question has not been answered? -loads!

    What has surprised me is that for 2 years this post had no replies, and then I post a reply then others do too.

    "its sorta frowned upon ..." - ok i'll avoid doing it in the future, thanks for the advice.

    If you have some good info to share you are better off creating your own new up to date thread. If it has some really good info ... Steve will often make a "sticky" so that it doesnt get lost in time down all the threads, for example the 555 timer one, the one on using LEDs etc and he will add to it as more info comes available

    not just on this forum ... most have that "thought" in fact some forums I'm on, offenders will a serious rah rah from the moderators and other users ;)
    its one of those things that falls into the "forum etiquette" box... like stealing some one elses thread for your own questions totally unrelated to the ongoing topic

    take care
    keep the solder flowing and dont pick up the wrong end of the soldering iron ;)
