We have an amplifier. A simple FET radio receiver circuit showing FET biasing. The gate is biased at ground potential through the inductor, and the source is held above ground by the current in ...

The dual JFET pre-amp provides tube-like sound ... Their blog post provides extremely detailed circuit analysis of every part of the design, starting from the power supply filter to remove ...

and “sonic attributes inspired by the flagship Relentless” preamplifier. Let’s tackle this progression bit by bit. Firstly, Dan D’Agostino has evolved its use of JFET transistors (which ...
