I’ve had this piece of test equipment for almost 50 years, since the mid1970s. It still works fine, but I no longer do the kind of work that requires an oscilloscope. Here’s your chance to own a piece of American manufacturing and technology from when US technology manufacturing led the world. I’ve been told it would be a “good museum piece.” Or maybe that person was talking about me?
The scope works, but the batteries are close to gone. The last time I replaced them, probably 20 years ago, they gave about 4-6 hours of use between 8-hour charges. I usually used the scope on 110VAC, but for field work (the original reason I bought the scope) the battery option is more than handy. The 500kHz bandwidth limits the scope’s function to audio work and similar sub-RF troubleshooting. It is in pretty good shape, physically and functionally. The rear cable wrap frame is broken where the power cord wrap, in 2 places, but the cables still store nicely on the scope. The case is in good condition and is included with the scope. Probes are hard-wired to the scope.

The interior pictures were taken from a couple of sites that described repairs on the Tek 214. I have not had this scope open for many years.
