When you're shopping in the test leads probes fixtures category, the first decision is whether you need a dedicated adapter for a specific job or a flexible probe that adapts to many signals. Two vintage-style accessories make that trade-off clear: the Tektronix 013-072 Diode Test Fixture Adapter and the KENWOOD PC-54 60MHz Oscilloscope Probe. Both support bench testing, but they serve very different workflows.
Quick Verdict
If your bench is set up for diode testing and vintage instrument restoration, the Tektronix 013-072 is the straightforward choice. If you spend more time probing circuit nodes with an oscilloscope, the KENWOOD PC-54 gives you the switching and bandwidth you need. The $70 gap between their listed prices mirrors that split: the Tektronix is the lower-priced listed option, while the Kenwood is the higher-priced listed option with more general-purpose capability.

Where Each Product Wins
- Tektronix 013-072 wins for diode testing, bench repair, and lab setups that already use banana plug connections. It is a dedicated component-level adapter with clear E and C terminal markings.
- KENWOOD PC-54 wins for oscilloscope users who need to toggle between direct and attenuated readings. Its x1/x10 switchable attenuation and 60MHz bandwidth make it a flexible tool for many signal types.
Product Notes
Tektronix Diode Test Fixture Adapter 013-072 Electronic Test Accessory Vintage
This is the specialist in the pair. The 013-072 is a plug-in diode test fixture with E and C terminal markings, two banana plug outputs, and a center jack. If you restore vintage instruments or do repetitive diode testing on the bench, this adapter gives you a clean interface to the component under test. The plastic housing with metal banana plug terminals is straightforward and functional, and the US origin makes it an easy fit for many domestic test setups. At the lower end of the price spread, it is the more economical way to get a dedicated diode adapter on your bench. Its limitation is the fixed scope of application: it is a diode test fixture, not a general-purpose probe, so if your bench work is mostly oscilloscope waveform checking, this adapter won't serve that need.
Vintage KENWOOD PC-54 Oscilloscope Probe 60MHz x1 / x10 Switchable BNC Texio new
The Kenwood PC-54 is the flexible generalist. This passive oscilloscope probe has a switchable attenuation ratio between x1 and x10, covers up to 60MHz, and ends in a standard BNC connector. That combination makes it a strong choice for engineers and technicians who move between vintage and modern scopes, and the Made-in-Japan build gives it broad compatibility with many instruments. It is the higher-priced listed option, but you're paying for versatility: you can probe signals directly and toggle between direct and attenuated readings without swapping probes. The downside is that it is still a single-purpose probe. It does not act as a diode test fixture and offers no banana plug terminals, so if your main task is component-level diode testing, you'd be better off with the dedicated Tektronix adapter.
Final Choice by Use Case
- For diode testing and bench repair: Choose the Tektronix 013-072. Its banana plug outputs and terminal markings make component checks straightforward.
- For oscilloscope work: Choose the KENWOOD PC-54. The x1/x10 switch and BNC connector adapt to a range of signals.
- When budget is the priority: The Tektronix has the lower listed price and covers focused testing needs.
- When flexibility matters more: The Kenwood's higher price buys switchable attenuation and broader probing capability.
