I have a question since I am new here and I don't know if this is the right forum to ask these questions or if I am wasting your time.
I am 67 and have a lot of Radios and Electronics I grew up with which puts a lot of them at 50 years or older.
A lot of the capacitors are obviously bad but this is my problem.
An example would be the Panasonic RC-7469 Clock Radio and the Panasonic RF-888 Radio.
I have others like a Canon L-162 Nixie Desktop Calculator 110AC, etc.
I have the Service Manuals to some of these and other electronics I have and grew up with and...

Good evening team,
I've been trying to learn electronics since the beggining of the year. My main goal is to fix broken consoles/laptops. It has been a very fullfilling journey and fortunately I've found my way around and I've already fixed a few of them.
While there's a lot of info online (this forum as an example) I would like to gather a few suggestions about books on electronics. I've already attempted to read a few ones, but to be honest I haven't found anyone that suits what I'm looking for. As an example "The Art of Electronics" is amazing, but there's... -
Howdy folks! I'm an artist in the video game industry, and my job entails making a lot of mechanical and sci fi assets. I thought it might be a good practice to start disassembling some electronics to be more familiar with how real electronics are manufactured and assembled, which is how i found my way to these forums.
When I started researching what tools I might need, I quickly encountered the warning "Some devices can maintain a potentially lethal charge in their capacitors, even up to years after last being powered on", which was enough of a scary thought for me to... -
Hello guys,
recently I watched Richard's video on YT (Learn Electronics Repair channel) with an explanation why lower input voltage than rated can also kill electronics components.
The vide can be shown here.
Now, I would like to learn more and I'm not sure that I understood exactly why this is happening.
It is clear to me that PWM chip will keep MOSFTES switched On longer (duty cycle is longer) and that they will dissipate more heat. I think this is not the main reason because MOSFET can probably work switched on for a long time. It is also possible that output...12-26-2022, 12:45 AM -
I have bought this Zener Diode for this project what size and wattage resistor value do I need to use to get near 50 watt output
I bought this from an eBay seller but unfortunately they only had one
I bought three from Vetco Electronics these are Sylvania ECG5185A 9.1@10w A to Stud what size and watt resistor do I need to use to get near 10 watt output
I bought three of from them to also make battery packs with this output power limit in mind
I want to use this battery pack and turn it into a 9.1 output battery pack output to eliminate using 9 volt battery...
