Investing in the best capacitors for tube amps is a crucial step towards enhancing the performance and longevity of your audio equipment. High-quality capacitors not only ensure smooth power supply and signal flow but also contribute to the overall sound quality of your tube amp setup. In this detailed guide, we will explore top-notch ...
This is equally true for the output coupling capacitors of the preamp. Certainly the designer of the circuitry must do the job properly, but given that this is accomplished, and given that the amplifier has adequate power and power-supply stability to do the job at hand, the purity of the sound is very dependent on the coupling capacitors used.
So if the at-rest DC voltage at the output of one internal stage is 5 V, but only 2 V at the input to the next stage, a coupling capacitor is placed in the signal path to allow audio to pass without upsetting the DC voltage difference. A capacitor is constructed from two metal plates in close proximity but not quite touching.
We've been auditioning coupling capacitors for close to 40 years now. The current king is the V-Cap copper foil Teflon; it is both neutral and extremely musical. As far as musical goes we've heard some extremely good paper and oil types but the problem we've seen with many of them is that they can develop electrical leakage.
By far the simplest arrangement is to use a large value capacitor - one that is at least 10 times greater than theoretically needed. While it would be nice to have the luxury of using the same ratio for speaker coupling caps, this makes the capacitor overly large and expensive.
The right value of coupling capacitor will usually be transparent. Wima FKP are expensive, really? Wima FKP are expensive, really? for 0.47uf even with low voltage, high tolerance they are much more expensive than MKPs on Mouser, they seem to be only available for backorder... might just be some inflation on FKPs for whatever reason.
In general, there are 3 types of capacitors that will be available in the values that are appropriate as AC coupling in most signal paths: electrolytic, tantalum and ceramic. Each has strengths and weaknesses. Electrolytic capacitors are generally the best performing for this purpose.

Coupled with a high-quality sound card (e.g., the Focusrite Scarlett 8i6), REW can be used to measure the distortion of passive components (e.g., capacitors and transformers) and even active devices such as equalizers and preamps.
I tried substituting or bypassing electrolytic capacitors with ''suitably'' selected values of mylar or polystyrene caps, so to cover as large an audio frequency spectrum as practicable. What I …
Over the years, with much experimenting and listening, I have found that a very major part of amplifier sound quality is directly due to the input coupling capacitors used. This is equally true …
If your budget has a bit more room, my very favorite coupling cap is the Copper V-Cap (CuTF). It has the best combination of sound qualities of any coupling cap I have tried, …
H ere on the workbench there''s one electronic component above all others that I deal with on a daily basis. Whether I''m refurbishing an old ''50s tube limiter, repairing console channel strips or hunting down an intermittent crackle in a microphone, capacitors are typically the star of the show, infamous for causing a broad range of faults in all sorts of audio equipment.
A coupling cap is a part of a filter and is if the amp is well built calculated to the right value. Changing value without the change of any other major parts as OPTs are not adviceable. Going from 0.33 to 1.5 will take your filter down into subsonic and probably damage your OPTs or in best case add distorsion.
From an economic point of view, coupling capacitor quality should be on a par with overall system quality (which is typically low).
Polyphenylene sulfide (PPS) is a good contender for SMT. Teflon (PTFE) is also excellent but hard to source. Electrolytics don''t have stable values of capacitance so only get used for DC-blocking and decoupling, no use in an active filter. They are fairly distorty, but bipolar electrolytics are somewhat better.
Analysis of the data converter output provides an easy way to compare capacitor contributions to signal-path distortion. The goal is to help you make informed decisions about capacitor …
I tried substituting or bypassing electrolytic capacitors with ''suitably'' selected values of mylar or polystyrene caps, so to cover as large an audio frequency spectrum as practicable. What I heard was much less interference of each instrument to another in an ensemble, from low volume to high volume levels.

So if you plan to keep your speakers for 15+ years, make sure you choose film capacitors. Since the electrolytic capacitor uses chemicals, it has a limited lifespan, so take this into consideration if you want to take the budget route. Film capacitors.
