Since you got more books than me, Do you have
anything on the
frequency response of 0b2 voltage regulator with the standard .01 uf
bi-pass cap? I was hopeing to use a few in my latest amp?
It's not above medium audio frequencies. (a few KHz at best).
The odd thing about gas-discharge tubes is that they work at all by sheer
probability.
If you can exclude all external and internal radiation (e.g. gamma
particles, light), a neon bulb won't fire at a voltage anywhere near its
spec-sheet level. The ionization avalanche needs an energetic particle or
photon to get it started. That's why neon bulbs fire at higher voltages in
a dark room than in a lit one. Manufacturers put a bit of radioactive
material (sometimes Krypton 85) in the gas mix to even things out. Very
old gas diodes tend to operate a bit more unpredictably than new ones
because a fair amount of the ionizing trigger material has decayed.
The curious upshot then, is that the time from the application of voltage
to the full ionization of a gas diode isn't consistent.
