What kind of capacitor do I need for a tube radio?
Usually, these are large silver multi-section can capacitors. In older gear or smaller tube radios, these filter caps are sometimes large multi-section axial wax and paper caps. A gnarly paper and wax Sprague Atom electrolytic capacitor pulled out of an old piece of test equipment.
Which electrolytic capacitors should I replace?
My personal rule of thumb is to replace all electrolytics in gear that was produced before 1970. Large can capacitors are still manufactured and available for purchase through many online sources. Purists who wish to retain the “look” of vintage equipment may opt to use these.
What happens when a capacitor on a car stereo fails?
As a capacitor ages, it starts to behave more like a resistor (impeding and destabilizing current flow) rather than like a capacitor (stabilizing current flow), and when it fails, it will likely destroy expensive surrounding circuitry! Considering that your stereo is at least about twenty years old, containing hard-to-find, if not impossible-to-...
Do capacitors affect tube amp performance?
Capacitors can also “leak” DC current and voltage – throwing bias off in different parts of the circuit which can affect the performance of tube and transistor circuits. Additionally, the hot temperatures inside a tube amp shorten their lifetime.
How do I choose a tweeter capacitor?
1:418:10PROTECT YOUR TWEETERS! Capacitors and WHY you need themYouTubeStart of suggested clipEnd of suggested clipLet's first start with finding F the frequency that we actually want to cut by using the capacitor.MoreLet's first start with finding F the frequency that we actually want to cut by using the capacitor. We want F to be greater than the resonant frequency of the tweeter.
Why do tweeters use capacitors?
In a simple passive crossover, we use a capacitor to limit the amount of low frequencies that make it to the tweeter. This does two things: 1) it protects the tweeter from the application of too much power at low frequencies, and 2) it helps us shape the response of the tweeter to match the response of the midrange.
Do you need an amp for super tweeters?
Do you need an amp for tweeters? If you just want better treble (“highs”) but not more clarity, volume, or power, a tweeter won't require an amplifier. You may even wire them to a regular car stereo if you don't mind less volume and power.
How do you wire three tweeters?
To connect your tweeters in series, ensure the negative terminal of the first one is connected to your amp's negative, the first speaker's positive is connected to the second one's negative, the third tweeter's negative to the fourth one's positive, and so on, ensuring that the positive terminal of the last speaker is ...
How do you choose a capacitor for a speaker?
Film capacitor selection is extremely important to achieve an acceptable quality sound reproduction. Consider the Root Mean Square (RMS) AC rating of the speaker system when selecting the appropriate capacitor since over voltage of a capacitor can result in the premature failure of the component.
Does capacitor increase bass?
Bass frequencies generally draw the highest supply current, so if the wiring to the battery is less than adequate, or the car battery is a bit old (sulphated) or low on charge, then a reservoir capacitor of adequate size across the 12V supply really close to the amplifier can make the supply stiffer (lower impedance) ...
Do you wire tweeters to amplifier?
Can you hook up tweeters to the same amp as a subwoofer? Here's the short answer: You cannot use tweeters on a monoblock (bass-only) amp or a subwoofer output channel using a low-pass crossover. You can use tweeters with unused amplifier outputs (channels) that are full-range.
How many watts is a good tweeter?
Tweeters normally only see a few watts of normal program material. Most have true power ratings of 2 to 4 watts, or 50 watts program material.
Is amplifying door speakers worth it?
It may not be a real necessity, but getting an amp for these is highly recommended. It may not only be about ensuring great sound quality as you drive around. You may find an amplifier most beneficial for your door speakers' overall 'health,' optimum performance, and maintenance.
What is the best frequency for tweeters?
Tweeters generally are good for around 3kHz or above, so 3kHz or 3.5kHz cutoff frequencies are usually great choices.
Why are my tweeters crackling?
It's clipping or an inadequate/malfunctioning crossover network on the tweeters.
How many channels do I need for 4 speakers and 2 tweeters?
In this case, you'd need 7 channels of amplification. 2 for tweeters, 2 for mids, 2 for rear, 1 for sub. There are plenty of good 5 channel amplifiers out there, but if you have the space, your best bet is to get a 4 channel amplifier and a subwoofer specific amplifier.
How does an electrolytic capacitor affect the performance of a tube?
Increased ESR (Equivalent Series Resistance) can gradually turn a capacitor into a resistor. Capacitors can also “leak” DC current and voltage – throwing bias off in different parts of the circuit which can affect the performance of tube ...
What is the purpose of filter caps in a power supply?
These large electrolytic capacitors in the power supply stage are known as filter caps – because their primary job is to filter the rectified voltage to feed different stages in the circuit a clean and constant supply of DC voltage.
What is the best way to repair vintage electronic gear?
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.
Can electrolytic capacitors be replaced?
While some repair techs will correctly tell you that electrolytic capacitors have some ability to “self heal” and “re-form” after years of abuse or disuse – There is no way to replace the dried out electrolyte.

2G What are our speaker sizes!?!?!!?
I have gone through a minimum of 20 different threads they all say something different. I know I don't have an infinity system because my doors are 6.5 but what're the tweeters in the dash and the rear panel speakers. How do I get a tweeter cover so it looks factory?
