As a big power supply cap ages they may lose their ability to properly reduce AC ripple current and that could cause extra stress on other components down the line. It would be wise to make sure they were in proper working condition regardless of any sonic benefits one would expect out of newer caps. :thmbsp:

Capacitors play key roles in the design of filters, amplifiers, power supplies and many additional circuits. Here''s a brief guide to the different types and the applications they''re best suited for.
This is the same power supply used on the Ender 3 Pro. Why upgrade? There are several reasons to upgrade your Ender 3''s PSU to a Mean Well: Noise: The PSU fan only runs when needed (usually <20% of the time), meaning a much quieter printer. Safety: MeanWell power supplies are more reliable and safer than the cheap stock unit. They use higher ...
Open menu Open navigation Go to Reddit Home. r/buildapc A chip A close button. ... Only reason I would upgrade a PSU is: The PSU is literally garbage unrated/too low wattage ... I think you''re far more likely to have failed capacitors which bring the power supply out of spec and/or cause a short to ground which would blow the fuse first.
Just install some additional capacitors of the same or greater voltage rating in parallel. Preferably, add some to provide bypassing where the power supply connects to the output transistors or IC. Beware that too much capacitance …
After giving the speaker and amp upgrades some time to settle, its safe to say the difference is impressive. The bass and treble stacks have a musical EQ sweep that makes getting a good balance simple; the amp definately needs the EQ, sometime requiring tweaks between genres, but to the unkowning ear this is clearly a good sounding hifi system.
A subreddit for practical questions about component-level electronic circuits: design, repair, component buying, test gear and tools.
mOhms refers to impedance. Generally, lower is better, but there''s rare exceptions. VRM capacitors must be low impedance similar to the originals. Lower impedance = more efficient capacitor = less wasted energy = less heat = longer capacitor life Ripple current is the fluctuation of current as a component draws/stops drawing power.
Part 1: The power supply capacitors It''s not a secret that one of the more economical ways of building a HiFi system is to purchase used or vintage gear. There''s a plethora of old gear available that can be found on the second hand market from companies such as Audio Research, Conrad Johnson, Luxman, PS Audio, Dynaco,
Increasing the power supply filter capacitance may help to this end and it is likely not to cause any stress type issues downstream (after the power supply filter capacitors). To be clear, I am not saying that an amplifier may not benefit from an increase in power supply filter capacitance of as much as 100 percent, but there are not guarantees.
My electronic experience goes back to the tube/valve age, the power supply was always referred to as B+. Per Wiki: B+, the plus voltage of a battery or plus voltage of an electronic circuit. The power supply caps smooth the ripple of a rectified supply and decouple the power supply conductors in both AC & DC fed types..
I used it once after swapping around supplies with the power on and upsetting it, yet further similar swaps didn''t cause any problems. While Farad supplies a short power cable to take the DC to the component they also offer upgrade cables to further enhance the benefits of the Super3, these come in two levels simply called level 1 and 2.

Often the major part of the power supply design, on the primary side, depends on the lowest DC bulk voltage after the HOLD-UP time in which the power supply can operate. This document presents a comparison between lab data, P-Spice simulation and MathCAD analysis of the same high frequency off line power supply. The power supply is a
Many Fender-derived amps use a choke-capacitor (LC) filter to supply the power valve screen grids. An LC filter is a second-order filter, so it provides steeper attenuation of ripple than an …
rent and filter capacitor value. The value of the volt-age ripple obtained is directly proportional to the load current and inversely proportional to the filter capacitor value. Aimed at system designers whose interest focusses on other fields, this note reviews the basic power supply design knowhow assumed in the rest of the book. 1/6
I see that the rectifiers are supplying a couple of odd size power supply capacitors. They are sized at 9300 uF and 150VDC (with a surge rating of 175 VDC). Does anyone know if power supply really needs the 150 VDC? I know the power supply tracks the voltage for the amp rails, but 150 VDC seems really high. Will a 100 VDC cap work?

A better solution is to wire large leak resistors (10k-100k) across the power supply capacitors. Then when you turn the equipment off, the powersupply will automatically ...
There are some videos showing how to adapt modern capacitors to fit and that would help maintain it''s classic look, but it seemed a bit fiddly to do. Also, you can see that in the base of the power supply there are numerous …
Generally its only electrolytic capacitors that need replacing, the most critical being the ones serving as filters in the power supply. Occasionally resistors that are stressed (like ones near the power tubes) can fail, and in some designs its a good idea to replace some of these with higher tolerance ones before they fail.
Replacing a capacitor on a power supply can extend the life of your electronic devices and maintain their reliability. By following this step-by-step guide and taking the necessary safety precautions, you can successfully replace a faulty capacitor, ensuring the continued …
There are multiple capacitors inside power supplies so not one simple answer. For the main reservoir caps, increasing the amount of capacitance will reduce the ripple …
When a capacitor is connected to a voltage source, like a power supply or battery, it causes a voltage difference between the plates, creating an electrical field. How does this happen? Electrons in the conductor …
Electrolytic capacitors intended for use in switch-mode power supply (SMPS) roles are rated for maximum RMS ripple current. This provides …

Personally I''d recommend Panasonic capacitors, every time I change an aluminium electrolytic I always change it for a Panasonic capacitor. The backlight of your monitor shouldn''t make any difference to the capacitors you need on your power supply.
Capacitors have improved, but capacitance values are no different than they were in 1974. A 1974 era 8,000uF cap still measures the same as a 2019 era 8,000uF cap. There''s a reason why Fisher engineers chose to use 8,000uF for their filter caps, and it wouldn''t be wise to go too much beyond that.
