5V4G is a green label Sylvania. 12AU7 and 12AT7 are Tung Sol from late 1950s. I used this for a while about 4 years ago.I tested it for sale and it powered right on and sounds good. It is all original so I would recommend having the large electrolytics checked out before putting it into regular use.
