Further info...  It starts quicker when I reduce the noise-source
amplitude to just 1 mV.  Also, I reduced the gains of E2-E5 to 90 to
simulate the way I'd build it, at least initially: using f.w.-rectified
115 V mains to charge electrolytic storage capacitors to the peak.  I get
a decent 100 KV at the 5th cycle with 160 V p-p applied; primary voltage
is about 1000.

I sometimes envy Europeans (& Brits) with their 220 V or so right out of
the handy wall-socket.

With the 1 mV of noise, oscillations start after about 8 us; with 0 V of
noise, it takes 80 us to get going.  Interesting...I wonder, in the
simulation, what gets it going at all in that case.
