Elmo Sound St 1200 HD M@O 2 track

Elmo Sound St 1200 HD M@O 2 track Was my grandfathers and he passed away recently. As i know he used these things quite frequently, but i am unsure of what type of working condition they are. I know everything he owned since this was his major hobby, was always serviced and well taken care of. I do not know how to operate this type of equipment, so i cannot test all the functions. Buyer pays all shipping costs within 3 days after auction ends. Any questions feel free to email, but again i am very unfamiliar with all this equipment i am selling.
