Shopping for turntables & record players can become a repair decision quickly: do you need one specifically named Numark TT-1520 component, or a Numark TTUSB turntable repair project with a broader stated feature set? The useful split is simple. The TT-1520 entry is priced at USD 10.00, while TTUSB is USD 49.99. That creates a USD 39.99 price spread, but the larger question is scope, not just cost.
Quick verdict
Choose the Numark TT-1520 slider cap if your repair centers on the named TT-1520 component. Choose the Numark TTUSB turntable if the turntable itself is the repair project and the listed interface features matter. The distinction is component versus complete turntable scope-not a promise of ready playback.
Price and scope comparison
| Item | Listed price | Condition or scope |
|---|---|---|
| Numark TT-1520 | USD 10.00 | Used; model TT-1520 |
| Numark TTUSB | USD 49.99 | For parts or not working; turntable |
Where each wins
Numark TT-1520 slider cap wins for a narrowly defined part search. Its title calls out the TT-1520 model and a speed pitch adjustment slider cap. That specificity matters if your repair target is that component rather than an entire turntable or a wider audio setup.
Numark TTUSB wins on connection-oriented scope. Its attributes name RCA and USB Out, while also listing a built-in phono preamp and pitch control. Those details make it the more relevant choice for someone seeking a turntable repair project involving both analog and computer-facing outputs. The USD 39.99 spread is the tradeoff for that broader described setup.
Product notes
Numark TT-1520 Turntable Parts - Speed Pitch Adjustment Slider Cap

The Numark TT-1520 Turntable Parts - Speed Pitch Adjustment Slider Cap makes sense when the repair need is already specific. Its title identifies the TT-1520 model and the speed pitch adjustment slider cap, and its attributes identify it as a DJ Turntable part. That narrow naming is the reason to choose it: you are targeting a defined component rather than buying around a broader feature set. The limitation is its scope as a part rather than a complete deck. The description also warns that parts may need cleaning. For someone who needs a full turntable or an accessory package, the named cap is a narrower match and should be selected for that exact repair job.
Numark TTUSB DJ Turntable USB Audio Interface TT USB UNTESTED PARTS/REPAIR READ

The Numark TTUSB DJ Turntable USB Audio Interface TT USB UNTESTED PARTS/REPAIR READ is the more feature-oriented repair choice. The description adds a 45 adapter and USB Cable, giving the project a clearly described accessory package. That makes it the better fit when the turntable itself and its included accessories are central to the repair plan. The limitation is the narrow test report: powering on is the extent of testing. The cartridge with cover is included, but the description says the needle may not still be connected. Choose it for a repair path built around the named turntable and accessories, not as a confirmed working playback setup.
Final choice by use case
- A TT-1520 component repair: Choose the Numark TT-1520 slider cap. Its model-specific wording gives it the clearest match for that narrowly defined job.
- A repair involving RCA and USB Out: Choose the Numark TTUSB turntable. Its listed outputs, built-in phono preamp, and pitch control align with that use case, though the powering-on-only test scope still matters.
- No specific repair target: The TTUSB is the broader turntable project, while the TT-1520 is the more narrowly identified component. Match the purchase to the repair scope rather than treating them as interchangeable record players.
