HP Hewlett Packard Oscilloscope 140A- Powers On/ Untested- Heavy Duty

About this deal

The HP 140A is a vintage plug-in mainframe oscilloscope, a CRT tube-type instrument dating from around 1963. It accepts a range of plug-in modules for functions such as time base and vertical amplification, making its performance highly dependent on whichever plug-ins are fitted. It is known for being very rugged and producing an extremely bright, crisp trace. This is an older piece of professional test equipment that appeals to electronics engineers, vintage instrument collectors, and hobbyists undertaking repair work on period audio or RF equipment. Users note that tube-based instruments of this type are generally rugged and relatively straightforward to repair. This example powers on but has not been tested for full functionality, and is therefore sold as-is, suitable for spares or restoration.
