I just saw this thread with a bunch of pictures of capacitors, and I'm tryn to find the ones that I need for my amplifier for my car but I lost the page it was on. Anyone know of this page I'm looking for?

theres shitloads of them. what else did it say?I just saw this thread with a bunch of pictures of capacitors -
Re: Help finding a thread
I got it, it was the video capacitor thread or something. I have an amp for my car stereo and I blew a couple capacitors. I think I can soder new ones to the board but I'm tryn to find which ones they are. I'm lookin for my camera I'm goin to post a picture up since this forum seems very helpful hopefully somebody can reconize them and help me find replacements.Comment

Find by serial number,model number or series
If you know the laptop serial or model number go to HP support https://support.hp.com/us-en/drivers/laptops .
Enter the serial number or model number and click submit.On the next screen you will have to enter the OS

Hi All,
I'm looking at upgrading my load resistors for power amplifier diagnostics and have a few questions:
1. is it possible to use e.g. a kettle element as a load?
and at the other end of the financial spectrum..
2. Electronic loads - would they work?
3. What's the gold standard method?
Many thanks. -
Hi Folks
Need some advice on how to test a subwoofer amplifier if i have access to only a multimeter.
Problem
I have a Boston Acoustics active Subwoofer (soundware S). Its rated output is 200W. But the output i am getting is very low i can barely hear/feel it even if put the gain at max. I replaced all the capacitors in the Subwoofer amplifier but still no change.
Is there anyway to test this without getting an oscilloscope/Function generator to see if the fault is with amplifier, driver or the source??
Any advice would be appreciated... -
Hello, I search this connector (oxydated).
It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?
Do you know how to find this connector please ? What is the exact name for find it ?

I am trying to repair a Yamaha DXR10 powered amplifier but finding it difficult because I have a smoking resistor which starts to burn as soon as I switch power on. (So I have it turn it off straight away.) The fuses don't blow and I connect a dim bulb which goes dim so no straight short to find. I have attached a marked up circuit diagram and I am looking for help in identifying the best place to look for what's causing the excessive power draw. Needless to say the amp isn't working. The mosfet circled in red was the start of my problem when it exploded. I replaced it and the resistor network...
