    Tektronix Model 502A Dual Beam Oscilloscope. I would guess that it was built in the late 60's early 70's because of it's use of both transistors (in the power suppy section) and tubes everywhere else.

    This scope has the unique feature of being a dual beam scope. Most CRT based scopes use a single beam CRT. The construction methods used in this scope are amazing as they used ceramic bars with silver coated connections points. The scope includes a built in calibration signal generator (square wave), .5mv - 50 Volt.

    This unit weighs approximately 40 lbs.
