Vintage Gear Maintenance
Here is an overview of how I do typical cleaning type maintenance on my gear. What are you guys doing for your gear?
Is your beloved vintage receiver or amplifier sounding a bit rough around the edges with crackling and static? Don’t fret! With a few simple tools and the magic of DeOxit (or your favorite cleaner), you can often restore its pristine sound quality. This guide will walk you through the process.
What You’ll Need (Gather Your Supplies):
- Screwdrivers: A variety of Phillips and flathead screwdrivers to remove the receiver’s covers.
- DeOxit Kit: This should include:
- DeOxit D5 (Red): For cleaning oxidation and contaminants.
- Caig FaderLube F5 (Gold): For lubricating and protecting controls.
- Others – Not everyone uses DeOxit, use what you think is best
- Cleaning Tools:
- Make-up brushes / Pipe Cleaners for getting inside small areas.
- Technical Cotton swabs (or Q-tips) for precise application.
- Clean Cloths or Paper Towels: For wiping or catching any excess DeOxit / Cleaner.
- Optional but Helpful:
- Small Allen wrenches for removing certain knobs.
- Jeweler’s screwdrivers for very small screws.
- Spoons (two) for gently prying off stubborn knobs or a pry tool.
- Straws, straight thin items for dripping cleaner
- Eye dropper
- Small containers or labeled bags to organize screws.
Let’s Get Started!
Step 1: Power Down and Unplug
- Crucially, disconnect your receiver or amplifier from the power outlet. This is essential for your safety.
- Also, wear any protective gear like safety glasses, etc..
Step 2: Remove the Top Cover
- Locate the screws securing the top cover of your unit. These are usually on the sides, back, or top.
- Using the appropriate screwdriver, carefully remove all the screws.
- Place the removed screws in a labeled container or bag. This will prevent you from losing them and make reassembly easier.
- Gently lift the top cover off the unit and set it aside in a safe place.
Step 3: Remove the Bottom Cover
- Carefully turn the receiver/ unit onto its side.
- Repeat the process from Step 2 to remove the screws holding the bottom cover.
- Again, store these screws separately and labeled.
- Lift off the bottom cover and set it aside.
Step 4: Assess Faceplate Access
- With both covers removed, examine the inside of the receiver, specifically the area behind the front faceplate.
- Locate the potentiometers (variable resistors, usually connected to knobs) and switches. They will have small openings or gaps in their casings.
- If you can clearly see these openings and can access them with the thin straw that comes with your DeOxit spray, you likely won’t need to remove the faceplate. Proceed to Step 5.
Step 5: Removing the Faceplate (If Necessary)
- If the potentiometers and switches are not easily accessible behind the faceplate, you’ll need to remove it. This process varies significantly between different models, so proceed with caution and observation.
- Carefully study how the faceplate is attached. Look for screws (often hidden on the front or sides), clips, or other fastening mechanisms.
- Take photos of the faceplate and its components before removal. This will serve as a valuable reference during reassembly. Make notes if necessary.
- Removing Knobs:
- Some knobs are secured with small set screws, usually accessed with a small Allen wrench. Loosen these screws before attempting to remove the knob.
- Some knobs simply pull off. Try gently but firmly pulling them straight out.
- For stubborn knobs, try using two spoons (or pry tool). Position the bowls of the spoons on opposite sides of the knob, protecting the faceplate with a cloth under the prying tool. Gently and evenly pry upwards.
- Once all fasteners are removed, carefully detach the faceplate. Set it aside in a safe place.
Step 6: Cleaning the Potentiometers (“Pots”)
- Locate the potentiometers you identified earlier. They are usually cylindrical or square components with wires connected to them.
- Attach the thin straw to the nozzle of your DeOxit D5 (Red) spray can.
- Carefully insert the straw into any visible openings or gaps in the potentiometer’s casing.
- Give a short burst of DeOxit into the opening. Avoid over-spraying.
- Immediately after spraying, vigorously rotate the corresponding knob back and forth through its full range of motion several times. This helps the DeOxit work its way inside and clean the internal contacts.
- Repeat this process for every potentiometer in your receiver.
Step 7: Cleaning the Switches
- Identify all the switches on your receiver (toggle switches, push buttons, rotary selectors).
- Attach the straw to the DeOxit D5 (Red) spray can.
- Locate any small openings or points of entry around the switch mechanism.
- Give a short burst of DeOxit into the switch.
- Immediately work the switch back and forth or rotate it several times through its full range of motion.
- Repeat this process for all switches.
Step 8: Applying Lubricant/Protectant (DeOxit Gold)
- After cleaning with DeOxit D5, it’s important to lubricate and protect the contacts. Use DeOxit Gold (Caig FaderLube F5).
- Attach the straw to the DeOxit Gold spray can.
- Apply a very short burst of DeOxit Gold into the same openings you used for the red DeOxit on the potentiometers and switches. A little goes a long way.
- Work the knobs and switches back and forth a few times to distribute the lubricant.
Step 9: Cleaning Input and Output Jacks
- Locate all the input and output jacks on the back of your receiver (RCA jacks, headphone jacks, speaker terminals).
- Spray a small amount of DeOxit D5 (Red) onto a make-up brush or pipe cleaner.
- Gently insert the treated brush into each jack and twist it around to clean the internal contacts.
- For speaker terminals, same process.
- For Gold plated jacks, use DeOxit Gold.
Step 10: Cleaning Other Connectors (Optional)
- If your unit has any other accessible connectors on the inside (ribbon cables, pin connectors), you can gently clean their contacts with a small amount of DeOxit D5 (Red) applied to a brush or swab. Be very careful not to damage any delicate components.
- You can also clean other connections like antennae or ground connections
Step 11: Reassembly and Testing
- If you removed the faceplate, carefully reattach it, ensuring all knobs and fasteners are correctly in place. Refer to your photos and notes if needed.
- Carefully replace the bottom cover and secure it with the labeled screws.
- Turn the receiver back over and replace the top cover, securing it with its labeled screws.
- Before fully closing up the unit, plug it back in and carefully test it. Turn it on and operate all the knobs, switches, and inputs. Listen for any remaining crackling or static.
- If you still hear noise, repeat the cleaning process on the affected controls.
- Once you are satisfied with the sound, fully secure all the covers.
All Done!
At this point, you can consider your maintenance completed. Assess if everything is working as expected. If not, you may need to take your unit to a professional tech for some repair.
Important Reminders:
- Always unplug your equipment before working on it.
- Use DeOxit sparingly. A little goes a long way.
- Control spraying DeOxit as much as possible to keep it on the areas needed.
- If you are at all uncomfortable with any of these steps, it’s always best to seek help from a qualified electronics technician.
Enjoy the renewed sound of your vintage audio system!
