Noise of Triode Driven Phono-Amps

Abstract

In the third Quarter of 2009 I had a long and intensive discussion with a Dutch friend on the noise production of his two-stage phono-amplifier. I didn’t believe in his output referred SN measurement results (FFT diagram shown in Fig. 17.1), because they always came up ~5–6 dB worse than the ones I have calculated. This fact became the starting point of a rather long lasting and extensive study on the noise of triodes and on how to handle them in a practical mathematical way. My goal: the difference between calculated and measured results should come-up within ±2 dB.
