I'm working on a tube buffer to plug into a insert on a mixing board to use as a "plugin" to warm up some of my tracks im using 1/2 a 12ax7 with a b+ of 300v 100k plate resistor and a 1k cathode resistor with a 100uf bypass cap. What impedance do I want for my input and output if I'm.going through an insert? Is 68k to high for the input of the buffer? Right now I'm using a 500k pot for input and one for output to control levels
