During our testing of the circuit, we noted that while a J201 provided more gain than an MPF102 or 2N5457, the overall tone was also darker in comparison. These key specifications encompass the electrical features of the Mpf102, such as its maximum drain-source voltage (VDS) and the associated current (ID). If a transistor has a gain of 1 times or 0 dB, does that mean there is no signal amplification? Out of ten (10) J201 average Vp: -0. I haven't really tried all that many myself. 24v 2n5952 - I = 1. Thank you. I will show the design step by step on how to design a JFET amplifier using any existing N channel JFET through Hello, Please let me start by saying KiCAD is AWESOME! Thanks to all of you who have worked so hard to make KiCAD the fantastic success that it is I am hoping this is the correct place to post this question, I am new to the froum.
