ECC808 is a special low distortion, low noise, high gain audio triode made by Telefunken, it has electrical characteristics similar to ECC83 or 12AX7 but does not pin out like ECC83 so using in an ECC83 circuit is certainly possible but socket wiring would be different. May 08, 2013 · This design is much like a Telefunken 12AX7 / ECC83 smooth plate but a bit shorter. This design provides plenty of gain while maintaining an extremely low noise floor.

Do different brands of tube sound different? Part II. No? Well maybe they do. Join me as the trip takes a wild turn in part II.. I’d been meaning to take this whole thing to the next level and do some tests that would, at least in some way, give an indication of performance when driven hard, all the way into serious clipping.
