This was bought and owned by my father. Everything he owned was in immaculate condition, and I have no reason to think this would be different. However, since I don’t know how to use one, or how to test it, I guess we’ll call it “used, as is”, though it does power up with no problems. — Vintage CONAR Model 255 Solid State Oscilloscope. Condition is "Used". Shipped with USPS Priority Mail.
