anyway to find out what year this sunn head was made, no obvious markings on the back

[EdBass]

A lot of old Sunns have an inspection sticker with a date on it somewhere on the chassis, or sometimes a date written on the chassis itself with grease pencil. If not, post a good picture of the front and somebody should be able to narrow it down for you.

Sometimes you can narrow it down with the transformer or pot codes too. A picture would be best to get started however.
