[QUOTE="Telmar, post: 162718, member: 4611"] Anode and anode resistors = red Grid and = yellow Cathode and cathode resistor and capacitor (just an option) = green Do you see the last stage ? The signal is taken from the cathode (green arrow), and not as before from the anode (red arrow) ! And there is no anode resistor and the cathode resistor is 50 or more times higher. This is the cathode follower, you use it if you want current not voltage (gain). You are absolutely correct, this circuit is able to drive lower loads ! That's why some designs use one as the FX send output tube. And it has a slightly different tonal characteristic, because it distorts different from the standard anode circuit. Some people think it's necessary for the tone circuit, but that's not true. Marshall did it this way, but ENGL usually did not, so it's not a must-have to drive the tone circuit. [/QUOTE]
