Denim 9,499 #1 Posted November 8 My electrical knowledge is limited hence the question. I have just bought a practice amplifier for my guitar. It will work using 3 alternative power sources. 1. Batteries x 6 2 power pack ( as you use with phones ) 3 9 volt adapter cable Will it be safe to the amplifier to connect it to the Thai mains by just plugging it in the wall socket. Thanks.

Bruce Aussie Chiang Mai 265 #2 Posted November 8 Should be safe adapters are dual voltage 110 and 240. 1 Share this post Link to post Share on other sites

Don't know yet as I got it on Lazada and am still waiting for delivery. Probably ok or they would not include the adapter but I am not sure of the country of manufacture.

Crossy 20,466 #6 Posted November 9 Do check the adaptor before plugging it in. That said, I've never seen a modern adaptor for sale outside the US that isn't "universal", all ours (and our LED lights) are "90-250V". Share this post Link to post Share on other sites

Bound to be something written somewhere in the manual. Share this post Link to post Share on other sites

Look on the label of the adaptor (modern manuals seem to be worse than useless). You may need a magifying glass but it will be there somewhere. 1 Share this post Link to post Share on other sites
