Where can I buy power and speaker driver board in the Amazon Echo

Hi @doc1963 ,

According to the comments in the ifixit Amazon Echo Power and Speaker Driver Board Replacement guide this part isn't available. (scroll down to Comments section at the bottom of the page).

It may be easier to search on places such as Ebay etc., for either a faulty Amazon Echo and hope that the board in it is OK or get a used, working Amazon Echo, as long as the price is OK.

You could try dis-assembling the speaker and then search online using the power / speaker driver board number only to see if there are any results. Use the ifixit guide to gain access to the pcb.

Here is an image taken from Step.6 in the guide, which shows what I believe to be the board number, (highlighted in green box). Unfortunately I cannot make out the entire number as it is partially obscured. No doubt you'll be able to see it better.

Hopefully this is of some help.
