If you're shopping for DJ equipment on a repair budget, the phrase "for parts" can be the start of a useful project, not a dealbreaker. It means you'll need to diagnose, test, and fix gear yourself, so the choice hinges on your skills and the price you're willing to risk. The four options here range from a $150 production mixer to a small set of replacement caps, giving you everything from a full rebuild to a trivial refresh.
Quick Take
The Furman DJM-8 is the most expensive and most unresolved: a production mixer that didn't pass a signal in the seller's test. The Numark TTUSB is the only turntable, and it can feed a computer through its audio interface, but it's untested beyond power-on. The Gem Sound DMX-2011 is a preamp mixer with four channels, also sold for parts. The cap set is the easy choice: new parts, no electronics knowledge required.

Decision Matrix
- If you want a complete mixer overhaul and can tolerate the highest price and most uncertainty, start with the Furman DJM-8.
- If you want a turntable that can send audio to a computer and includes a built-in preamp, the Numark TTUSB fills that role.
- If you want the smallest possible spend to replace worn controls, go for the cap set.
- If you want a mixer project with room for multiple sources, the Gem Sound DMX-2011 is the one to watch.
Product Notes
Furman DJM-8 DJ Production Mixer for Repair / Parts
The Furman DJM-8 is the project for someone who expects to troubleshoot a signal path. It's a production mixer sold as-is, and the seller could not get audio through it. That makes the chance of an electronic fault higher than a cosmetic issue. If you're comfortable opening up a mixer and tracing the circuit, the top price here buys you a serious rebuild. The limitation is the unknown: the fault could be a simple broken wire or a failed internal module, so your time and parts budget may go beyond the initial outlay. This is not a quick fix.
Numark TTUSB DJ Turntable USB Audio Interface TT USB UNTESTED PARTS/REPAIR READ
The Numark TTUSB gives you a turntable that can feed a computer through its USB output while also offering RCA output, and the built-in phono preamp means you don't need a separate phono stage. It powers on, but that's where testing stopped. The cartridge is included, though the needle may no longer be connected, so you'll likely need a replacement. The 45 adapter and USB cable are part of the deal. For a music setup built around vinyl and digital recording, this is a strong fit, but it's still a repair candidate.
5Pc/Set Knob EQ Fader Cap for Pioneer Numark Rane AKAI DJ Controller Mixer Parts
The knob and fader cap set is the new, low-risk item in this group. It includes five plastic caps meant to replace old or lost EQ/fader caps on compatible gear, including Pioneer, Numark, Rane, and AKAI. That makes it a straightforward way to restore grip on worn controls. The catch is the mix color: the caps are a mix rather than a matching set, so they may not look uniform on the panel. With a price at the low end of this range, the financial downside is small, making it an easy first buy if your current caps are worn out.
Gem Sound DMX-2011 4-Channel DJ Stereo Preamp Mixer - UNTESTED / FOR PARTS
The Gem Sound DMX-2011 is a compact preamp mixer with a four-channel layout and a stereo design. It was built for DJ setups that need to control several audio sources and adjust levels during transitions. The tradeoff is the honest condition label: this unit is unverified and sold for parts. That makes it a better fit for someone who wants a mixer to learn on than for a working gig. If you need four channels but don't need a heavy full-size console, this is the smallest mixer project in the price range.
Final Recommendation by Use Case
- Pick the Furman DJM-8 if you have the diagnostic tools and the patience to rebuild a production mixer from an unknown fault.
- Pick the Numark TTUSB if your main goal is transferring vinyl to a computer and you're ready to replace a needle and check a belt drive.
- Pick the Gem Sound DMX-2011 if a mixer project suits your bench and you're comfortable with an unverified unit.
- Pick the cap set if you just need to restore grip on a few controls without taking on another repair.
