"Dun Mei Audio" OTL Amp - anyone seen one before?

Posted by mmcc73 on September 11, 2020 at 07:43:38:
Hi all - I bought this recently in a local online auction. I have not yet picked it up so I don't yet know if there is anything in the chassis or not - I'm really hoping there is. At this point I'm assuming it is an OTL amp because of the OTL sticker on the front.

I'm curious if anyone has ever seen an amp like this. My googling has turned up very little. The chassis is available empty on Aliexpress, and I have not been able to find any pictures of one being used for an OTL amplifier.
