The Glowing Noisemaker Reloaded

Burkhard Vogel had an article in  the fifth Linear Audio (Vol 4) about calculating the noise production of triode gain stages. In this article Burkhard develops simulation models using the free LTspice IV simulator. By using data sheet numbers and a suitable 1/f noise corner frequency, Vogel develops models that lead to the same result as the calculation procedures explained in Volume 4.
