[QUOTE="Mars, post: 919997, member: 817"] Hi All here is a schematic of the circuit I propose: [IMG]https://i.imgur.com/s2JT3DQ.jpg[/IMG] with both controls flat, the EQ looks a bit bumpy [IMG]https://i.imgur.com/fKCUQze.png[/IMG] but with treble and bass turned down a bit, a flat line can be achieved [IMG]https://i.imgur.com/RH9cfHc.png[/IMG] I am considering adding a cathode follower directly after the second triode, either single triode with cathode resistor, or double triode aikido style, that will cancel some PSU noise. Any ideas? [/QUOTE]
