Early examples of 1- and 2-in. oscillographs and oscilloscopes are sought after by collectors and can range in value anywhere from $70 to several hundred dollars depending on model and condition. Even though these 1930s examples are not really useful on the bench anymore, oscilloscopes like the Supreme 535 shown above often command higher prices at auctions. Collectors will pay these prices due to the artistic styling of the etched front panels and quality of the cabinets used. The design and looks make these early oscilloscopes collectable as display items and are a nice addition to a test equipment or antique radio collection. Most single-trace vacuum-tube oscilloscopes manufactured in the 1940s and 1950s have little collector interest or resale value at this time. They can usually be found at swap meets for just a few dollars. These can be great buys if you want to dabble at vacuum tube and CRT circuits. I have noticed that the roll-around carts for some of the tube oscilloscopes built in the 1960s can be sought after as much as the scope itself. These scopes will take up a lot of valuable bench space if not used on a cart and due to size, not as many have survived in storage over the years.
