A shame Tascam engineers didn’t think to make a cradle for the battery. That said thank you for posting this 🙏

Thank you for posting.

Thanks for the tutorial!

Hi, I'm using a transformer from 110 > 240 Volts. But the transformer is heavy and stands on its feet upon the floor. In Europe, the only reliable electric cords are the multiplugs that have a button on/off. Unfortunately, the transformer cannot be inserted vertically to get into these multiplugs, but I have to use a single normal electric extension. But those seem thin and take up to16 Amps. I do not want to burn the whole machine, also would you please be kind to tell me if such a thin wire max 16 Ams could be okay for the 688, please ? I don't know if my question to you is clear enough to get an answer and advices ? Thanks.

Do you know if the 644 has the same battery?
