Just want to share a most useful tool I recently got to check caps, resistors, transistors and whatnot.
It's a version of an open source project, but has proper case and banana jacks for test leads. It couldn't be easier to use - just plop the suspected part in and press the test button. It even has a de-charging port for caps.
The cap in the picture was replaced during a repair, and the thingie confirmed my suspicions - while it still has capacitance, the ESR is way out - 7 ohm, but is supposed to be less than 1. In my defense, the cap looked ok from above
Picked this one up at bang-good for 25 USD shipped.
