"If I change this tube for that one and then solder in a different transistor and use active electronics instead of passive, maybe then I'll getthat sound." People start experimenting with their gain staging,headroom, and all kinds of things to emulate the good old days. ...
Amprobe has been inventing and manufacturing electrical test products for generations. They have one of the largest selections of multimeters andamp clamp metersin the market and are a good mid-range alternative. Their specialty is clamp meters (since they invented them), but they also produce a...
1947: Transistor On December 23Bell LabsengineersJohn Bardeen,Walter Brattain, andWilliam Shockleygave the first public demonstration of thetransistor, an electrical component that could control, amplify, and generate current. The transistor was much smaller and used less power than vacuum tubes and us...
