I see, I thought that it's because it is "more tube like" but what you say makes senseManfred wrote: ↑22 Sep 2021, 06:57The following concerns the comparison with Power-MOSFETs.Why is the LND150 so common? I see it more than any other mosfet
I also ended up using a jfet buffer powered by the 12V for the heaters
5 -10 times smaller input capacity.
Smaller noise figure.
Much smaller forward conductance, thus more suitable for the source circuit.
Smaller case (TO92).
I see that you have decided to use the JFET circuit.
Yeah and from what I hear it works very well
