    testing voltages across components in an AC circuit

    Hi, i'm learning about checking the voltages across components during fault finding. I know how to calculate the total resistance and current of a circuit and thus use that with ohms law to calculate the voltages but I'm now wondering what if the circuit was AC. In particular im looking at audio...

    log or lin for eq cut and boost control?

    Hi, Just wondering which potentiometer taper is generally used for the cut and boost control on an audio equalizer. I know that for normal volume controls we use logarythmic taper but i'm wondering is this the same for let's say... a 'bass' control on a hifi amplifier which has a centre point...

    replacing 4.7k pots with 5k on negative feedback op-amp circuit

    Hi, I'm doing a repair job on a friends PA mixer/ amp. i've done the essential fixes (dodgy NPN accompanied by a blown resistor) However, I'd quite like to replace all of the pots (24 of them) for sturdier ones as the ones currently on there are proper wobbly and it will make a HUGE difference...
