---

### **Pros of the Fisher MC-735**

1. **Versatile Cleaning and Maintenance**

- **Tube sockets and pins** Removes oxidation and corrosion without damaging contacts.

- **Speaker cones and voice coils** Helps restore performance by cleaning dust and grime.

- **Capacitors and resistors** Can be used to clean and restore passive components.

- **Chassis and circuit boards** Effective for removing carbon buildup and oxidation.

The kit includes specialized brushes, solvents, and tools tailored for audio repair, making it more precise than generic cleaning kits.

2. **Non-Abrasive and Safe for Sensitive Components**

Unlike harsh chemicals or abrasive tools, the MC-735 uses **mild solvents and precision brushes** that won t scratch or damage delicate parts. This is crucial for tube amplifiers, where improper cleaning can lead to permanent failure.

3. **Cost-Effective Alternative to Full Replacement**

Many audio components degrade over time due to oxidation, dust, or carbon tracking. Instead of replacing entire tubes, capacitors, or transformers (which can be expensive), the MC-735 allows for **restoration of existing parts**, extending the life of equipment.

4. **Works on Both Vintage and Modern Audio Gear**

- **Solid-state amplifiers** (for cleaning contacts and chassis).

- **Speaker systems** (cleaning voice coils and cones).

- **Mixers and preamps** (restoring switch contacts and circuit boards).

This makes it a **versatile tool for DIY audio technicians and hobbyists**.

5. **Easy to Use with Clear Instructions**

Fisher provides **detailed manuals and guides** that explain the proper techniques for cleaning different components. The kit includes **applicator brushes, cotton swabs, and solvents in droppers**, making the process straightforward for beginners.

6. **Prevents Future Issues**

- **Intermittent connections** (due to oxidized contacts).

- **Reduced power output** (from dirty tubes or capacitors).

- **Unwanted hum or noise** (from carbon buildup on chassis).

By keeping equipment clean, users can avoid costly repairs down the line.

7. **Affordable Compared to Professional Services**

Hiring an audio repair technician to clean and maintain equipment can be expensive. The MC-735 allows **DIY users to perform professional-level maintenance at a fraction of the cost**.

8. **Compatible with Other Fisher Products**

If you already own or plan to use other **Fisher audio restoration products** (such as the **MC-730 for capacitors or the MC-740 for transformers**), the MC-735 integrates well into a broader repair workflow.

---

### **Cons of the Fisher MC-735**

1. **Limited to Cleaning and Maintenance (Not Full Repair)**

The MC-735 is **not a repair tool** it cannot fix broken components, replace faulty parts, or solder circuits. Users must still have access to **replacement tubes, capacitors, or wiring** if those are damaged. For major repairs, additional tools and expertise are required.

2. **Solvents Require Proper Ventilation**

The cleaning solvents in the kit (such as **isopropyl alcohol and specialized audio cleaners**) can be **strong-smelling and flammable**. Users must work in a **well-ventilated area** and avoid open flames or sparks when using them. Improper handling could pose a fire or inhalation risk.

3. **Not Suitable for All Materials**

- **Sealed components** (e.g., some modern solid-state chips).

- **Rubber or silicone parts** (solvents may degrade them).

- **Wooden cabinets** (cleaning solutions could damage finishes).

Users should **test solvents on a small, hidden area first** before full application.

4. **Learning Curve for Beginners**

- **Over-cleaning tube sockets** can strip lubrication, leading to dry contacts.

- **Using excessive force with brushes** can bend delicate pins or scratch surfaces.

Beginners may need **practice or guidance** to avoid mistakes.

5. **Solvents May Not Be Available Long-Term**

The MC-735 includes **small bottles of solvents**, which may not last for extensive use. Over time, users may need to **repurchase solvents** or find alternatives, adding to long-term costs.

6. **Not a Substitute for Professional Diagnostics**

If an audio issue is **electrical (e.g., short circuits, blown transformers) or mechanical (e.g., loose wiring)**, the MC-735 won t diagnose or fix the root cause. Users may still need a **multimeter, oscilloscope, or professional technician** for deeper troubleshooting.

7. **Some Users Find It Overkill for Minor Maintenance**

If you only occasionally clean **tube sockets or speaker cones**, the MC-735 might feel **more expensive than necessary**. A simple **contact cleaner (like DeoxIT) and a soft brush** may suffice for basic maintenance.

8. **Potential for Misuse Leading to Damage**

If solvents are **not rinsed properly**, residue can remain on components, potentially causing **shorts or corrosion**. Similarly, **aggressive scrubbing** can damage delicate parts. Careful application is essential.
