Not necessarily. Consider the tolerance of a capacitor''s capacitance, especially in tone control applications. A capacitor with a tight tolerance (low range) will maintain the specific capacitance during use, whereas loose tolerance capacitors may sound different if you are playing indoors or outdoors.

Get PriceRun Capacitor Selection Guide
Start vs. Run Capacitors. Start capacitors give a large capacitance value necessary for motor starting for a very short (seconds long) period of time. They are only intermittent duty and will fail catastrophically if energized too long. Run capacitors are used for continuous voltage and current control to a motor''s windings and are therefore continuous duty.
Get PriceCoupling capacitors in a CE amplifier
I know that those C2 and C3 are used to isolate DC from the input and output. Capacitors are always open to DC(w=0) and since the equivalent impedance of a capacitor can be expressed as 1/jwc in $begingroup$ With nothing to pull-down the output side of C3, the initial DC bias point assumes a DC voltage drop across C3 as zero, so …

Get PriceWhich type of capacitors to use in which setting?
They have special properties, that''s why people (including me) prefer to use a film capacitor to replace them. If not, I''d use a new OS-CON or a low leakage- low esr electrolytic. ... The input of the amp was at about 1 volt DC, and the head cannot have DC on it otherwise it will mess with frequency response and can damage the recording on …
Get PricePurposes of A Capacitor In Car Audio
When the engine is on, the alternator powers your car''s electrical system along with the battery, amplifier, capacitor, etc. All of them are some sort of load that adds an extra burden on the alternator. This means the more load you have in …
Get PriceCommon Emitter Amplifier and Transistor Amplifiers
In Common Emitter Amplifier circuits, capacitors C1 and C2 are used as Coupling Capacitors to separate the AC signals from the DC biasing voltage. This ensures that the bias condition set up for the …

Had restored many vintage equipment like vacuum tube and transistor pre and power amps as well tuners and musical amps. On old tube amps often the coupling capacitors (foil type) are electrical leaky. That is the first to do. Second the electrolytic caps. Sometimes the power supply caps can be kept when meauring OK in terms of leakage …
Get PriceList of 25 Applications of Capacitors | Uses of Capacitors
Audio: Capacitors are used in many audio applications, including crossovers in loudspeakers, tone controls in amplifiers, and blocking DC signals in pickups for musical instruments. 13. Sensing: Capacitive sensors use the changes in capacitance that occur when an object is brought near a capacitor to detect the presence or absence …
Get PriceCoupling and Bypass Capacitors
Coupling capacitors (or dc blocking capacitors) are use to decouple ac and dc signals so as not to disturb the quiescent point of the circuit when ac signals are injected at the input. …

In car audio systems, large capacitors store energy for the amplifier to use on demand. An uninterruptible power supply (UPS) can be equipped with maintenance-free capacitors to …
Get PriceHow to Pick Audio Capacitors – Charrette & Beget
Hi! The geometry of the capacitor doesn''t matter at all to the sound, so you can use any capacitor that is (1) 3.9uF (2) rated 100V or more and (3) non-polarized. If you pick one that is also "Low ESR" it would better approximate a perfect L …
