Hi,
I'm looking to get on Aliexpress a hot air soldering station for hobby use, nothing too fancy, just something "reliable" and budget-friendly.
Any recommendations for a "good" cheap one that gets the job done?
Thanks in advance -
I've just been repairing some (very) old speakers with a loud hum that occurred as soon as you powered them on regardless if any actual audio is played through them. I work in a School so it's 99% likey that the Teachers have hardly ever turned the power off on them for well over 10+ years.
As you can see the top large capacitor on the right has a bulge on the top so defincately needs replacing. As the one next to it is exactly the same capacity and voltage I planned to replace them both.
What is your advice/opinion on whether or not on old(er)... -
Hi all,
I have an old Apple II monitor to restore and I do have a big variac. I've always wondered whether a variac is a good idea to power on equipment which has been unpowered for (likely) decades?
When it comes to analogue stuff, I suppose it's ok and I'm probably going to see the device slowly coming back to life with a lower voltage applied.
But I suppose this won't work for devices with digital components in it as they won't work unless the proper voltages are applied?
In case of an old monitor, it is safe/good for the monitor to...10-13-2023, 02:47 AM -
Hi All,
For some background, I passed an OND in electronics in the 80's. Life took me elsewhere, and I've finally got around to using it practically. My interest is in vintage electronics.
My question is, other than a multimeter, what is the most used and useful piece of test equipment ?
Thanks !
