If you ever wanted to build your own tube amplifier but you were intimidated by working with high voltages, [Marcel]’s low-voltage tube amp design might spark your interest. The design operat… ...

I = 5,000 watts ÷ by 240 volts; I = 20.8 amps; Because the electric space heater on a continuous load could operate for three ...

NAMM 2025: AmpRx has unveiled Brownie, an voltage optimising power supply that’s designed to give your tube amp exactly what it needs to perform at its best. Now, AmpRx has made voltage ...

This circuit’s bandwidth, with a voltage-feedback amp, equals the gain-bandwidth product divided by the noise gain. For instance, if you have a voltage-feedback amp with a gain-bandwidth product of ...

When designing op-amp circuits, you’re often using a chip with 2, 4, 6 etc. amplifiers on the same die when you only need 1,3,5… so you end up with an extra.

Amps - Current. If voltage is the pressure of the water, amperage is the diameter of the hose carrying that water. Amperes, or amps, named after 18th and 19th century physicist André-Marie ...

Small car batteries work for 40 ampere-hours, while larger ones will easily last for 50. More oversized vehicles, like trucks, use batteries with 75 ampere-hours capacity. Car experts recommend paying ...
