Re: LG 23LS7D - DOA nothing.....
I can put one 1/2 watt 2R2 or 2 -1/2watt 4R7 whats your thoughts on that?
I got 10,000 resistors here, 1/4 watt 1/2 watt, 1 watt, 2 watt, 5 watt, some 10 watt, couple of 20 watt..... and another 4000 SMD various sizes and NO MATTER WHAT I NEVER HAVE THE ONE I NEED ARRRRRRRRRRRRR!!!!
I can't even pair the 1 watts to even get close.. OMG I'm about to rip a few power supplies from my pile apart... back in a fewLast edited by Doc38343; 08-01-2017, 06:19 PM.Comment

Re: LG 23LS7D - DOA nothing.....
try the 2.2 1/2 watt, if it survives, then either install the correct one or put the 2 4r7 in parallelComment

Re: LG 23LS7D - DOA nothing.....
used a 4.7 1/2 watt piggy back on a ceramic 1 watt 3.3 ... I used the meter till i found a pair that's 2.1.....

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:

Hello,
First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.
I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.
I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

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... -
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,... -
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?...
