Replacing electrolytic capacitors is one of the most common ways to repair (and maintain) vintage electronic gear. This article will explain what these capacitors do and discuss a few different approaches for replacing them. What are Electrolytic Filter Capacitors?
Here are some fundamental rules for replacing electrolytic capacitors in circuit boards. Replace with exact type if available. Replace with capacitor that has the same capacitance (uF – microfarad) as the original. Replace with capacitor that has the same voltage rating or higher. Use higher temperature capacitors when possible (105c).
Now we will start searching for replacement capacitors. First, go to the website of your electric components distributor and go to the Aluminum Electrolytic Capacitors section. Narrow the search by entering the capacitance (uF) and voltage (V) values of the old capacitor. You may also want to check the box to only show components that are in stock.
Another option to consider when replacing electrolytic capacitors in your gear is to purchase modern axial capacitors with high voltage ratings. Axial caps in particular are useful in power supplies constructed on turret boards, common on vintage guitar amps.
First, go to the website of your electric components distributor and go to the Aluminum Electrolytic Capacitors section. Narrow the search by entering the capacitance (uF) and voltage (V) values of the old capacitor. You may also want to check the box to only show components that are in stock. Narrow the search by price.
Press the tip of a heated soldering iron directly onto the solder joint on the back of the circuit board that is holding the old capacitor down. Hold on to the capacitor itself with your other hand. As the joint melts, you can feel the tip of the iron fall into the hole of the circuit board.
