This is the best match for that amp.

Re: New Caps for amp power supply
They are 10,000uF 50V 50mm dia. 80mm height? People use 10,000-12,000uF 63V.
Computer grade electrolytics are very expensive. Apex Jr. store (DIYAudio) has surplus computer grade electrolytics, store is in Torrace CA USA.
Snap-ins are much lower cost, but need a PC board to mount to, unless you glue them down. Pic of one kit for the Quad 405, but not sure if still available.
They make a sonic difference so resist temptation and don't cheap out.
Ripple current is at audio frequencies, so you need a 20kHz ESR spec that is decent, not just a mains freq. spec.Attached FilesComment

Re: New Caps for amp power supply
I am new here, once i can post a thread i will discuss mine,
to help the poster
Farnell UK, or Mouser of Digikey if you wish to get other parts, they offer 60$ AU free postage. Farnell is like Element14 australia we dont have much options
I am not that informed
how about United Chem Com SMH or KHM capacitors or Cornell Dubilier 380LX, which are nice and cheap at Mouser atm

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,... -
I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails
I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time... -
I have a 15 - inch Retina MacBook Pro from the mid - 2014 model. Here is the link: https://www.badcaps.net/forum/showth...light=820-3662 . The battery broke some time ago. After I removed the battery and plugged in the original power adapter, the MBP could boot up normally. However, when I checked with IntelPowerGadget, I found that the CPU speed was limited to 0.8 GHz, and it ran very slowly. Later, I found a solution on GitHub. There is an open - source project called cputune that can set the CPU running speed. So I can now run the MBP at full speed. But another problem...
