Update: Unit has the following tubes, all but one seem original
1 - Telefunken 6U8, with diamond-shaped logo, West Germany
1 - 6GH8A Japanese, can't make out logo but it has a satellite-type logo with bisecting orbits
1 - Scott by Amperex 5AR4/GZ34. Made in Holland
4 - Scott 7591, US made
4 - Telefunken diamond logo ECC83/12AX7, West Germany, with metal covers
There is also slight damage to the front left edge of the cover that can barely be seen in the photos. It has been rubbed hard, and you can see a little metal under the brown fabric cover, but the metal is not dented.
