RE: "frequency compensation" and "sound shaping"

With a Schottky biasing a wimpy triode such as a 12AX7 , it may work but the impedence will be far higher due to the low current through the diode . Y ou would also need far more diodes stacked to get the required bias . I seem to remember Naz proposed a solution using a star power LED for around 1mA or so (archives?) .
