Flicker noise is not the same as random walk noise, the spectra differ.
Using an AC coupled generator (eg a sound card) filters out the low
frequency content.
Zeners and transistors (biased at low current) can be used to generate
flicker noise directly at least for low frequencies where it dominates.
Generating random walk noise is more difficult, integrating white noise
is one technique that can be used (at least in principle).

What is the best good available transistor or other parts? All parts he
tested where just to good.
A conducting zenier diode across the input of an amplifier.
