I have an original 1969 SUNN 200s in really good condition considering it's 42 years old. Only changes that have been made are the previous owner added a 3 prong power cord and a new peavey transformer. The exact date on the sticker on the chassis from E-TEST is 6/6/69. Looking to trade for an original early 70s Model T. Will send pictures of the amp if anyone is interested.
