Science Buddies: "Ask an Expert"

For How Loud Can Paper Speakers Get?, we were told to buy Jameco Part no.: 380156, 12 V, 2 A DC wall adapter, but it is not available.

We cannot tell which of the Jameco “substitutes" is a viable alternative.

Can anyone help?

Thanks.

Hi - did you also buy the mini audio amplifier from Amazon linked in the materials list? If so, any other 12V, 2A wall adapter should work as long as the barrel plug dimensions are the same - 2.1mm x 5.5mm. For example this part from Amazon should work: https://www.amazon.com/Chanzon-Switchin ... 07HNL5D56/

Thanks very much.
