Vintage Kenwood Stereo Amplifier How To Clean VintageUnfortunately, old and neglected components are often found in pretty rough shape, which means youll need to learn how to clean vintage stereo equipment before use. The steps below will walk you through cleaning the interior of any audio component using a basic contact cleaner. Contact cleaner is a spray or liquid product that is designed to dissolve corrosion on metal electronic parts, typically the main cause of scratchy and popping sounds while moving volume controls or intermittent rotary or push-button switches (for speaker selections, modes, source) headphone or microphone jacks, etc. While all contact cleaners work on metal-only parts, most will actually destroy plastics and safe lubricants found inside and outside of almost every volume control potentiometer and switch. You can usually purchase a safe bottle at a decent electronics store or over the internet though it is important to be certain shipping of the product is approved by the shipping service as many contact cleaners are flammable and sometimes cannot be shipped certain methods or to certain locations.

Vintage Kenwood Stereo Amplifier Cracked Controls SoEquipment damaged or destroyed by contact cleaners which are not safe on plastics can sometimes end up on the internet (where you cant try before you buy) with no reference to seized or cracked controls so be careful to ask sellers if the knobs still turn or slide freely without excessive force or have shaft or neck breakage hidden by glued knobs etc. You can typically buy a few basic models of low-cost modern reproduction volume controls over the internet and test different contact cleaners on them to see what works and what doesnt before risking your stereo equipments rare original pieces. To make sure that no electricity will be flowing through the internal components while you clean, unplug the audio equipment. Do not simply turn the power switch off; remove the plug entirely from the wall outlet as death could otherwise occur. Please note that a qualified technician should be at hand, and while many are unable to choose contact cleaners wisely, many can help you avoid a shock from a charged capacitor which can at least shock or burn your hand from skin to conductor contact even while the unit say unplugged for a long time. Be careful and look-up electrolytic capacitors for information. The case of the component is usually removed by loosening a few small screws or bolts. Often these screws will be located on the sides, back, and bottom of the unit. Not all screws on a given surface are for the casing so look carefully at what you are unscrewing so as to only remove the casing screws. After removing them, set them aside or put them into numbered containers in order to match them up with the correct holes you can put stickers on afterwards, taking pictures can help too, and gently lift the case away from the chassis.
