Did anyone figure out how to use a modern Op-Amp (not 748) in a mosfet shunt stabilizator for a tetrode screen power supply? This is what G3SEC said in his original article: "This is a very high-gain
Thank you Jim. Also Roger - W7TZ. You both show an arrangement I haven't seen before. Most likely I'll use it. _______________________________________________ Amps mailing list Amps@contesting.com ht
Hi, Could someone please confirm the output impedance of a classic tetrode linear amplifier does'n change as plate voltage sags or swings? I imagine it must be the same because no tetrode amp design
I've built an amp roughly based on the Pa0fri design (with some changes that include better stabilisator for the screen voltage - thanks to this group, 3000V - under load, HV PSU from an old R-140 mi
