Longtime contributor Bob Meister from Hamden, Conn., writes in response to Tom Osenkowsky’s recent contribution with respect to equivalent series resistance (ESR) and the Sencore LC-75 Z-Meter being ...

There’s a problem with collecting old tube amps and vintage electronics – eventually the capacitors in these machines will die. It’s not an issue of a capacitor plague that causes new electronics to ...

Our recent discussion about checking capacitors for equivalent series resistance continues with tips from two engineers with plenty of field experience. The first is from engineer Ed Treese. Ed writes ...

As electrolytic capacitors age, their internal resistance, also known as “equivalent series resistance” (ESR), gradually increases. This can eventually lead to equipment failure. Using this design, ...

Smart Tweezers ST5S-BT is based on the popular ST-5S model of Smart Tweezers; this model offers the most features and functions as well as a basic accuracy of 0.2%. The Bluetooth enabled model can ...
