Tools needed to perform proper maintanance of audio electronics
Selection of proper tools is very important. Otherwise, damage to device can occur and repair can be difficult. In this article, the most often tools are listed and explained.
Use only top quality screwdrivers, otherwise you can damage screw head. Screwdriver is one of the things that is worth to invest. I’ve been using one Vessel screwdriver for more than 10 years, every day, and it still has no signs of wear.
If you cannot release stuck screw, then try to unscrew it while pushing screwdriver towards screw as firmly as possible. This is also the reason why quality screwdriver must be used.
Always select screwdriver with correct tip, usable for given screw.
High grade watch oil. Use only small drop to lubricate metal parts, like bearings, levers.. Do not use it to lubricate plastic parts. It is important to use oil that dries very slowly, otherwise it will change to sticky substance after some time.
Using “any mineral oil” helps for while, may be several years, but then it will make situation even worse.
Grease – different grease should be used for lubricating metal parts and different for plastic parts. When poor quality grease is used, it can dry and glue parts together.
It depends on your knowledge and also on how deep you want to go with troubleshooting. Basic tool is multimeter. Advanced tools are oscilloscope, signal generator, quality soundcard.
Drills are used for repairs, when you need to join two cracked parts together. In this case you can drill small hole to both parts and fix them together with tiny brass wire. I use 0.6 to 0.8 mm for that.
Use it to replace old one, or use it as aid for when doing troubleshooting, modifications, etc.
