Hi Morgan!
Yes, Inside the box are just the battery (the negative impact), a potentiometer, speaker and a little wire ...
Unfortunately, I do not Mineoro DCH85/88 / or similar (2010) that I could show you its complete interior.
The posted photos I took directly from the great Greek Forum
www.psaxtiria.net
Thank Greek friends who put them there!
If there is new information put them here on the forum.
Regards!
