Choosing a diode test fixture often comes down to how your bench is wired. If you are shopping for test leads, probes, and fixtures, you may already know whether you prefer banana plug connections or some other lead style. The Tektronix 013-072 diode test fixture adapter is a dedicated vintage option built around banana plugs, and it asks you to commit to that format.
Quick verdict
At $89.99, the Tektronix 013-072 is a practical choice for a bench that already uses banana plug leads. The E and C terminal markings give clear connection points, and the two banana plug outputs plus center jack align with standard bench leads. The bigger question is fit: this is an older accessory with rectangular connector housings, so it will appeal most to buyers who appreciate vintage Tektronix design or who prefer visible, labeled terminals over modern plug-in modules.
Who it suits
This adapter suits electronics hobbyists, lab repair technicians, and anyone restoring vintage Tektronix gear who wants an era-appropriate fixture. It is also a reasonable choice for bench setups where banana plug leads are already the standard, because you can connect it without special tools. It is less ideal if your test leads all use non-banana connectors or if you expect a modern, enclosed test module.
What stands out
The unit is a black plastic fixture with metal banana plug terminals and beige/gray rectangular connector housings. It carries the Tektronix, Inc. 013-072 label and offers two banana plug outputs plus a center jack. The terminal markings E and C make it easy to identify where to connect the device under test. A copy of the paper sheet shown is included with the accessory.
Meaningful trade-offs
The main trade-off is the connection style. Two banana plug outputs and a center jack are convenient if your bench already terminates in banana plugs, but they define how this fixture gets used. If your existing leads use another connector, you will need an adapter or a different lead set. The vintage design also means the rectangular connector housings have an older look, so this is not a direct visual match for newer fixtures.
Tektronix Diode Test Fixture Adapter 013-072 Electronic Test Accessory Vintage
The labeled E and C terminal points plus dual banana plug outputs make this a straightforward accessory for diode testing on a banana-compatible bench. The same connector format is the limitation: your test leads have to match the banana plug style before this fixture becomes useful.
Bottom line
Buy the Tektronix 013-072 if you have a banana plug bench and want a labeled diode test fixture with a vintage Tektronix name. If your test leads are not banana-compatible, this accessory will not be the right first piece of your setup.
