#amplifier

My "Nixiez" : I am finally wrapping up a project I started in 2017 ! A DIY clock and audio amplifier duo. Here's the github page with the code and more details than I have the patience to share here : https://github.com/dmeat-art/DMT-Nixie-clock-amp #DIY #electronics #arduino #nixie #nixietube #nixieclock #audio #amplifier #VUmeter #cnc #lasercutting #woodworking #Conceptart

Random electrical engineering question. I am looking at building an RIAA preamp (for a record turntable), and most of the circuits out there use a NE5532 dual low noise opamp. However, I have a LOT OF 4741 opamps (a lot). Originally destined for the L1011 aircraft, lol. My analog design skills having significantly atrophied since college (cough cough), what specifications on an opamp (aside from noise) are important for this stuff? I suspect I have to re-calculate gain and values for a different opamp? (also, bandwidth on the 4741 is 2.5Mhz... NE5532 is 12Mhz... so I assume they aren't going to be equivalent). #electronics #opamp #amplifier
