Please ensure that battery polarity is shown correctly in picture showing connections. I ordered 2 and will check polarity on adjacent electrolytic to be sure. Update spelling to battery... All is good. RED lead is usually (+) and BLACK is (-) Just wish YOU success and looking out for you and for your customers. Cheers... I watched the video and looking forward to obtaining units to interface with my vacuum tube amplifier. Should be exciting to use the remote to play my mp3 songs.
