Re: Rotel Caps Questions and help request.

Dimmer will not work since it chops up the sine wave (beside, you cannot use dimmer with inductive load-the transformer-anyway). You need to use VARIAC if you want to slowly bring up the voltage while you monitoring the current draw, so you will need AC meter or Clamp-0n AC Amp meter.

Seasonic B12 BC-550 – barely 2 years old and with BAD CAPS already!

by momaka

I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.

For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

Rotel RA-810 Fader Caps

by bermo96

Hi,

I rescued an old Rotel RA-810, after a little cleaning and new thermal grease for the transistor it works like it should.
But unfortunately the fader caps are gone, they are nice aluminum caps, so I want to try to find something similar.

Does anyone know if this amp shared these fader caps with other brands? Or if there is something similar on the internet?

The picture is for the balance cap, the faders have the black line running through the cap.

Identifying caps on an old Zoom 9000

by Paxman_Swede

Hello!

I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

I have studied the board and...

Help with switching power supply caps

by captain150

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,...

Gigabyte GA-6OXT :: caps question

by Foetuss

Good evening

I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

But I was also suprised about the bigger boys, which are 330µF 25V.
Could it be they used 25V caps because they were cheaper / available at that time?...
