He demonstrated it in use, and even goes as far as to show it running an audio power amplifier driving a small speaker. For the dedicated student of op-amps, may we suggest further reading as we ...

There are plenty of tube amplifiers now being manufactured ... An NE5532 steps in for the op-amp buffer role, making for a very simple circuit. Power comes from a set of four 18650 Lithium ...

The graphs show a high nominal output current of 5 mA to better display the higher end of the current-amplitude range. Depending on your application, you can optimize each circuit's dynamic impedance ...

The amplifier used in the BTR17 is a THX AAA 78+ that was previously used in FiiO’s M23 DAP. The four-channel, fully balanced design uses eight op-amps in parallel for robust power with a ...
