Recapping a AOpen AK73 Pro(A). There are two 10v 3300uf caps on the board, but I only have 6.3v 3300uf caps. I measure 5v at the cap... that should be safe to replace with 6.3v, right? The voltage shouldn't fluctuate that much...

Ludicrous gibs!

Re: replace 10v with 6.3v?
bet its 2 lelon at the vrm input.
i used 6.3v parts as i was out of the 10v ones.
its 5v there so plenty safe. -
Re: replace 10v with 6.3v?
Good to go. I've decreased voltages on occasion after measuring and testing. For example: The 3900uF 10v caps on a Shuttle FV24 or FV25. They never have any more than VCORE voltage on them, so its perfectly safe to replace those 10v caps with 6.3v caps. However, never do this unless you're absolutely sure. It will always be safe to increase from 6.3v to 10v though.<--- Badcaps.net Founder

Re: replace 10v with 6.3v?
I figured I was safe since I measured the voltage, but I wanted to make sure. Is there ever a situation where voltage through a cap will change during the normal operation of the motherboard?Ludicrous gibs!

I found these, i would only like to try them on a board to see if it post. It don't post at the moment, i guess there are 9 6.3v 3300uf that can be broken. Is these low or high esr? I did not find info on the web.

When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.
Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.

I've just been repairing some (very) old speakers with a loud hum that occurred as soon as you powered them on regardless if any actual audio is played through them. I work in a School so it's 99% likey that the Teachers have hardly ever turned the power off on them for well over 10+ years.
As you can see the top large capacitor on the right has a bulge on the top so defincately needs replacing. As the one next to it is exactly the same capacity and voltage I planned to replace them both.
What is your advice/opinion on whether or not on old(er)... -
Hi, I try to replace a VRM Alpha & Omega on a GIGABYTE 3080 TI Eagle,
marking BKU0 but i can't identify part number for buy it
Someone can help me ?
do you know here i can find Sch and brd file for this card ?... -
I have purchased an 100-240v AC/5v 2a DC adaptor from aliexpress,and a month ago It smelled burning when I plugin it powerstrip.
Since then, This AC/DC adaptor have been out of order.
But A few days ago,I replace 0.5 watt resistor with 1 watt resistor(1ohm) in this adapter.
After replacing resistor,It succeed to recharge all of android phone.And When I measure voltage on the two pins of USB port,It shows 5.5v
Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
And Is there any possibility that it will suddenly explode as well as to be out...
