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 ...

Capacitors are essential components in electronics, primarily used for bypassing and decoupling. Depending on the capacitor type and its application, it is prone to aging and failure. Detecting a ...

The circuit in Figure 2 combines the sink currents of both the Output and the Discharge pins, which allows us to double the output current. Resistors R3 and R4 are part of the load, they limit the ...

Capacitors are classified according to their dielectric’s type. Electrolytic capacitors are popular in power electronic circuits, due to their high volumetric efficiency and excellent price ...

Broadcast consultant Tom Osenkowsky recently constructed a panel with two vu meters and a DPDT switch. The switch allows him to configure the meters to display conventional Left and Right channels or ...

[Dr Ali Shirsavar] from Biricha Digital runs us through How to Select the Perfect Output Capacitor for Your Power Supply. Your switching-mode power supply (SMPS) will require an output capacitor both ...
